REA #9 | Hitchcocks Motorcycles 19t Sprocket Swap | Royal Enfield Classic 500 | Install & Test Ride 

Not sure if anyone mentioned this, but worth pointing out that the Euro 4 model ( 2017- 2021) comes with a 17T standard. I did not check so went from a 17T to a 19T with a 38 rear sprocket and it feels terrible ! revving hard to get off the lights, lugging, so need to swap down to an 18T to get it right.... perhaps you want to point this out to your viewers ? Thanks again for the instructions

I run good quality OEM Reynolds chain on my Triumph Tr-6 with a hard tail and magneto.A piece of the frame broke and also cracked in two places. The Reynolds chain was holding the back of the bike together. You could see it shaving the back sprocket. Rigid frames are very easy on chains because they are always at the proper tension. I have had my Triumph Tr-6 with a hard tail and magneto for 40 years.

Excellent information regarding both the installation of the 19t sprocket and the differences it makes. Thanks for taking the extra time to capture, edit, and post this video! You've created the most comprehensive amount of information about the Classic 500 that I've found on RU-vid.

Great video! I enjoyed watching how you replaced the 19 tooth sprocket but I enjoyed it even more driving it on the empty roads and listening to the Enfield. Rarely that I watch a complete video of someone else driving the bike but this one I did!👌🏻

Holy moly, this was supremely helpful. Thanks for all of this!

Great Video I did this mod a few years ago best mod I have done to my classic 500.

I did an upgrade like this to my '95 Enny 500 after improving the breathing of my motor. Back then I'd never heard of Hitchcocks so I made my own sprockets. I installed a smaller back wheel in the quest for a brake that suffered less heat fade (Honda CB350 back wheel with mods) but it was a mistake. The change in rake angle induced by the lowering of the rear end affected handling negatively. Lacing a CB750 hub to the original rim to get better braking while retaining the original wheel diameter seems to have become "one of those projects"... I must admit, watching your vids this evening has given me a bit of a kick in the ring mate.

Great vid, informative and entertaining. So jealous of those empty dry roads though mate. The antithesis of what you would expect in Sheffield UK😃

Just saw this video, good review and good mod! Just a few days ago I caught the boat from Geelong the Devonport to pick up a 2000 model Iron Barrel Bullet, I nearly sent you a message. I wish I had as I just looked it up and you're only about 20 ks from Devonport. I also own a 2014 UCE Bullet, love both those bikes they have so much heart. Good on ya mate, ride safe and watch out for the skippies and the random wildlife jumping out in front of you!

Great video, buddy! I just got out there and changed the spark plug today from the factory Bosch to the NGK BPR6eix. The cap was a nightmare to get off, I don't think it's ever been removed since being put on at the factory. Put the new plug in...cap would not go on for the life of me. I struggled and did everything I could. Decided to put the Bosh back in...cap went on no problem! Start looking and realize the Bosh has a threaded top and the NGK had a cover around the threads! Grabbed some pliers and twisted it off...went on a like a dream afterwards. Funny moments like that make it memorable!

It might be a lot of work but it still looked fun to do the swap and the results sound perfect

Also, you've got some beautiful terrain there!

You should be employed by the Tassie Tourist Bureau! I enjoy your honest practical videos. I am about to buy a new Bullet so I appreciate your videos.

Have now fitted 20 tooth front sprocket and a 110/90/18 rear tyre RPM has dropped from 3600 to 3100 at 100km/h, with vibration reduction plate, makes a relaxed riding

I did the same on my 2018 model and wished I had gone up to 20 teeth, I'm sure it would pull it, as the torque is great with the Hitchcocks free flowing exhaust system, I also fitted the Carberry crank bearing kit at the same time. Mine will cruise 70-75 easily on dual carriageway top whack is about 85 before rev limiter kicks in. Love the bike

I'll agree that the 19 tooth front sprocket was one of the best "bang for the buck" upgrade you can do. Period. -Madd Man

I told you you`d like it. I too thought it cut down quite a bit on the vibrations. The bike I test rode reminded me of my old 2003 Bonneville T100. Not as powerful but still better than the stock 500.

My Sportster is still on the original set of drive sprockets after 25 years. I get 100,000 miles out of a belt . Much cheaper in the long run.

it's an awesome improvement on my 2010 C5 , a couple others I really recommend if you want to virtually eliminate vibrations are the bearing plate from Carberry, works extremely well, and drilling out your plugs in the handle bars and almost filling the bars with pellet gun pellets or shotgun shot and then putting on bar end mirrors, which also eliminate a lot of turbulence around your helmet from the stock mirrors. feels like a completely different bike.

Thanks for this , very helpful 👍

I'll add that to my to do list next oil change, just been coast to coast here for £4.80.. about $7 haha went to the bugout vehicles meet . Can see me and the bike on Richards channel " bugout vehicles UK" I'm in the vid he put up today but there will be another short one soon just on me and my setup for survival and fishing and hunting , riding to the veterans protest in Manchester tomorrow because our boys are being put on trial for following orders 40 years ago so it's gonna kick off..vids will probably be under "rolling thunder UK" ..we are shutting down all major cities till they listen. Great vid buddy.

Beautiful riding Country 👍

I like your work and machine.

She sings a great tune. There's quite a few of them appearing now here in the U K.

That's a lot of stripping to get to the sprocket dude. I hope you enjoy the results after that Herculean effort.i best most folks wouldn't dare.good vids again bud

Bloody awesome, Bewdy mate

I thought it might good to get confirmation . Regards Peter

It sure is a lot of work to get to that sprocket mate. Although, that is one of the easiest performance mods that will give you instant results 👍

19teeth front made your bike much more cruising friendly I have swaped 16teeth with 18teeth of 500cc of my classic 350 the initial is little bit slow but crusing at 110kmph its much smoother then before

Looks like a good mod..However, my 2016 has an 18 tooth front sprocket. So I just changed the rear sprocket from 38 to 36 tooth, still get the 2 to 1 ratio, but about one third the cost and don't have to mess around pulling the case. Just pull the rear tire and change the sprocket. Much easier and same result.

looked up google maps, what a great rural area Sheffield is - spoilt for choice of nice cruizy back roads.

great stuff! thank you

Quite a job swapping the sprocket out, but clearly can see its worth it. Well done 👏

I did fit a 19T to my 2015 Classic EFI-500 only to find it reduced ultimate top speed and put a huge gap between 4th and 5th so that joining a motorway I had to rev 4th up to 75mph in order change up with any hope of acceleration in top. All the gears are shifted up so that 2nd and 3rd used for tight corners and bends now had to go down a cog, and that gear was too low. With the gearing raised the back wheel lacked sufficient power in top to get 85mph even though I have a few extra ponies, struggling to get over 80 at times. With the 19T the motor felt like it was labouring and slogging at times. I swapped back to the 18T. With the 18T re-installed it will happily potter along at the national speed limit (NSL) of 60mph and the gears are now back in all the right places for bends. Motorway NSL is 70mph, it will happily cruise at that and then some when asked, as the cars go north of 80. Have I shown you this before? It's no burn up but a fairly gentle ride uphill on a relatively twisty rural A-road. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6FZPqf3qI3M.html

Man that graphite chrome looks damn sexy

thanks for the video

Thanks so much for filming and recording your process! I just had one question, it doesn't look like you needed to swap out the stock chain or the rear sprocket for this 19T front sprocket swap, correct?

Thanks for the work you put into making this vid mate! Still have half the mind on getting a classic 500 here in San Francisco CA. Looks to fit the bill for city filtering but the higher highway speeds in the Bay are not for the faint of heart (70-95mph). Would you say that the 19T makes a 250k trip at 100kph-120kph manageable? Once in awhile getaway type of trip

Thats exactly what I was planning to do to my bike. Glad that you went before me. :-) About the tools, I was thinking what you gonna use that hammer for. Ahh now I see... Do you really need to remove the exhaust system? And removing the nut on that sprocket, I would just use my impact wrench. I can see that your bike is using the old chain tension system. Nice that you didn't need to change the chain. It would have been nice to see where the fuel is cutting off in second, third and fourth gear. Mine is cutting off at 60 on second, 80 on third and 110 on fourth gear. Anyway, thanks for the video and the effort you put on this video. Cheers.

Wow thanks for your vid it seem a better bike and l was listening to sound of engine not laboured At all must try this l think it’s a bloody good idea thanks

Mmmm love the mods you have made Tas. But not sure on that one lol.have spoken to people who have done it and a lot have changed back as they preferred it standard. I suppose it's what you like!!

Hi Fella. I find first gear is too short on my Euro4 C5 (2019). Would going up to a 18t front sprocket give me a taller first? Thanks.

Hi m8, just a quick one, did you encounter any problem with the sprocket tab washer? and was there a seal on the case which needed changing due to the outer case being removed? cheers.

Have you tried it with a passenger ? I'm 2 m and 134 kg my classic says hey one at a time whenever I get on it......but less RPM on a longstroke engine is always a good idea just don't want to lug it too much and beat up the rod bearings out of it.

Thanks for the video. Do you recomend changing the chain as well to a different size?

Hi m8, when fitting the new sprocket was there enough slack in the chain? (did you have to wait until it stretched enough to take the larger sprocket) I take it you kept the original chain on and just moved the wheel forward then? cheers

Hi, great video. Do we need to replace engine oil fully everytime we open rh cover for replacing sproket or for any other purpose?

Hello, I enjoyed the video. I am riding the Royal Enfield Classic 500 in Korea. Does the vibration decrease if I replace it with 19T?

So can assume that unlike changing the back sprocket where a link or two might have to be removed, you can keep the same length chain by going up one tooth on the front? What is the red line on one of these? About 5500 to 6000?

Love this motorcycle and the mods youve done. Im curious to know if it has lost a little torque from before?

nice one bro...can i get an information about your silencer which you have installed in your bullet... I've just loved with it's sound...

19 teeth... Good luck, Happy Thumping.. Dug.. Dug... Dug..

I am yet to decide on doing this but a question, does it at all affect the low end torque by replacing to 19 tooth? Thanks!!

FYI, the 2019 models have a 17T sprocket standard, so an 18T upgrade is what Hitchcock's recommend. I could have gone for a 19T (= two tooth upgrade), but that might be a bit excessive for the capabilities of the bike?

I am looking to get the 19 t for my bullet 500 standard, for the carburetted version. I would greatly appreciate your response for two of my questions which are as follow: #1 Did you have to make any modifications to the chain (did you need a longer chain or was this a direct fit) # 2 What size is your rear sprocket? How many teeth are on them? Thanks!

Sounds like you could have almost gone to a 20 tooth on the front ( I wonder if anyone has). I suppose the rear disc brake models would make things a bit easier to play around with gearing choices. Good job though!

How well does it run in higher altitudes and canyons. Is there any difference in the way the bike pulls.?

Hallo there....I'm impressed with your modifications and I'm owner of royal Enfield bullet 500....want to know what short of engine oils you use in your classic 500. Thanks

What are the changes you note when the sprocket is changed...

Hello, I'm a young man using Classic 500 in Korea. I would like to translate the motorcycle inspection and ask you a question. Currently, classic 500 bikes can hear the tappet noise. The noise seems to be terrible. However, I can't hear that sound in your image at all. How do we solve this problem?

Boa noite! Você pode me ajudar tenho uma classic aqui no Brasil mas os mecânicos não consegue solucionar meu problema a moto desliga e ninguém descobre será que vc sabe o quê pode ser

Woa, so much work to get to the sprocket... On my DR 650 Suzuki, a 3 bolt cover and thats it. Interesting video though. Isnt too tall a gearing now ?

Hi, could you kindly tell me what’s the size of that giant nut holding the sprocket?

What is the socket bit size for removing front sprocket

Does it only increase the top speed or also improves the pick up performance?

Hey :) Did you use any sealant or gasket to close the crank case cover?

Hey 👋, how do you know what RPM is it doing I also have a classic 500

Top swap for your riding conditions, in the long run fuel efficiency would come into it also i think ? Would you recommend something like this for my Duke, as you know they are high revving engines. Love the pops when letting the revs down on the ride lol. I notice 2 cushions under the knees these days haha... CHEERS m8 : ) ahhh milo 👌👍

Any difference in top maximum speed ?

What size was the nut that held the front sprocket in place?

What is the sizes of the socket for removing the front sprocket nut ?

good night, my name is George, I live in Brazil. I would like to know where I can buy this 19t sprocket for Royal enfield classic 500 year 2017 with ABS.

Hi! I have a classic 350. Would this mod be helpful for me? I do a lot of Riding in the mountains of southern Philippines

Hello iridetas I have orderbedrag a 19t sprocket too as I got enthousiastic on you video hoever I opened the right side and to my surprise there was no 18 but 17 tooth sprocket strange as in the manual they talk about 18 't I have a classic 500 2020 I am going to put it on anyway because I think that the torque of the bike Will safe me I don't mind the topspeed

Did you need to buy a longer chain ?

Is a belt drive available for the RE 350 ?

Where’s a good place to look for what accessories are available? I absolutely adore this bike, but I don’t think I could get one without a trip meter. The only way I’ve found so far to do that is replacing the speedo with a digital one which goes very against the aesthetics of the bike.

I love my classic 500 but this bike is so difficult to work on compared to my previous bikes...

Hi. I'm thinking of doing this and not clear what the standard sprocket tooth count is on a Euro4 C5? Should be the same as yours. So I paused the video and zoomed into the sprocket you'd removed. I counted 19 teeth?! What witchcraft is that 🤔 Anyhow, anyone know for certain what I would be running as standard?

How come your bike does not have any tapet noise?

definitely a lot of work

Hey mate. What size nut is on the sprocket spline? Looks huge

Has it reduced vibration ?

Isnt that breaker bar meant for a Scania 18 wheeler?? ;)

Oh and did you need a new gasket on the transmission cover?

Guys i have 2017 model... Will this suits the bike.. actually changing of 19t sprocket what's the uses pls tell me... I have classic 500... Pls reply guys

How would this cope with a pillion?

I just installed a 20 tooth sprocket this drops the RPM from 3600 down to 3200 at 100 km/h or 60 m/h

which your RE500 ABS or non-ABS ???

Ktoś wie gdzie moge kupić taki zbiornik paliwa chromowany oryginalny do Bullet 500?

How many tooth was the stock sprocket?

topspeed with new sprocket?

Please tell me about torque and top speed.

could you confirm the Hitchcocks part number for that sprocket as 92722/19. Cheers...

a lot of work. it is what the bike needs, however... esp here in the United States... 65mph for any distance is punishing on this bike. I'd think that this and the Carberry anti vibration plate would be a good combo.... Your exhaust is obviously non-standard.

what's top speed and rpm's?

Not such a job compared to doing the same job on 1961 AJS 350. Personally id get a spare casing and cut the rear part off so i wouldn't have to drain the oil.

What is the part number you used. There arr several different 19th sprokets Mine is 2012 c5 classic

7:55 tool Size I'm curious (mm)

You wouldn't want to pay your dealer to do this mod. Would cost a shitload in labour costs.
