2021 GSXR 750 gets Full Brock's Performance Exhaust and ECU FLASH!!! MUST HAVE MODS 

134whp, 58ft/lbs @2:10 - 125whp. All stock. @5:26 - 125whp. Full exhaust, oil, adj chain, pair mod, no flash or tune. Lost few hp low to mid range from being lean. @10:00 - Basemap/mail in tune, fuel changes, exhaust valve delete, TB butterflies de-restricted. Too much fuel, no hp gain. @12:50 - 131whp. Tailored fuel for the Brock’s system. @13:41 - 133whp. Fuel is spot on, played with ignition timing. @14:54 - 134whp. Didn’t video dyno run. Raised rev limiter and other “small adjustments”. Over all, 10whp throughout the entire rev range!

I want to clarify some things for some of the guys who are disappointed in the final power figure for the bike once flashed.... I'm going to explain this stuff in generalities without getting into nitty gritty math. So, your average (*NEW*) liter bike is somewhere between 440 and 460 lbs wet and they generally produce, (once flashed) 180-200 whp..... A flashed 750 with a pipe will make 135 hp at the rear wheel but it literally weighs 419 lbs wet and it is simply disingenuous to ignore such a significant weight difference. So, you have to factor in the power to weight ratio. No, it isn't as fast as a 1000 but you can't simply compare 190 hp vs 135 hp without factoring a 30-40 lb weight difference.... That's what makes the gsxr-750 such a remarkable machine is it's power to weight ratio! To give a sense of how truly light the 750 is, I owned a Kawasaki zx6r that is actualy more modern, and more recently updated then the GSXR 750 yet even still it actually weighs more then the GSXR at about 435 lbs wet and it is over 100 cc's less then the gsxr..... With the 750 you are riding on a 600cc Chassis (literally) with an extra 150cc's of engine displacement and only 9 lbs of added weight. The truth is there is no other bike like the GSXR-750 available on the market today. It's a unicorn, perhaps even a Relic, but it holds a special place in the hearts of many motorcycle enthusiasts. If I had to guess the real power differential while factoring weight it would only be a difference by a factor of about 30 hp as opposed to the actual difference which is something around "60"... (roughly).

Beautiful bike Chris Suzuki paired with the Brock full exhaust sounds awesome! Great job on schooling us on your tuning expertise on the ECU .

Hi Chris, greetings from here in England, another brilliant video, can I just add, I absolutely love your opening montage it is soo cool man 👨😎

Looks great, sounds great and the performance is incredible! 😎

I am ur Jamaican fan and I love everything that says Suzuki keep up the good work one love bro

Ohh wee rick, that is cleaaann 🔥 great vid man nice shots good talk, love it!

I just bought one of these today!! It does sound very quiet... New system coming soon ((: Ill be mailing my ECU in. You guys rock.

God Bess you bro. Love the precision and honest teaching.

Everyone who installs full exhaust and doesn’t tune needs to see this video.

Thanks in advance I love all your content by the way.

Nice Tune, Like the sound.

We love what you do street / race track keep doing your thang South Carolina Cheraw!

Absolutely outstanding 👍🏼👍🏼

Love the channel !! I would like to suggest dyno a bike stock, with power commander V with auto tune then your tune. Would love to see the auto tune vs your talents at tuning. Keep up the great work and videos !!!

sounds insane I love the sound of it I luv pops & bangs on bikes

Great sound ,nice looking motorcycle ,way to go!!

That looks dope mr. Mafia....

Chris,I'd love to see some drag content with one of these bikes. Thinking of building a 750 just for something different!

sounds awesome especially compared to stock

M4 GP is my favorite on the 750 but that Leo Vince with the Bazzaz sounded better then them all! My dude Chris ✌🏾

what is important here is that most people of average knowledge can see that $2000.00 could be in their savings account instead of Flash Brock's account

From watching the first run of the bike stock , it would be interesting to see what the bikes stock exhaust can offer with all the restrictions lifted on the bike and tuned as that would be more of a fair test between factory exhaust system and brocks pipe .

You are the best thank you very much for the videos

My K8 750 full arrow thunder exhaust system, KnN filter . ECU flash n Dyno tune . 143 rear wheel HP . Ripper

This totally proves you are a world class tuner. I cant wait till you get us a 2021 zx10r flash for tuning

I have this exact bike and same mod ima get it ecu flashed by you !!

everyone has a dream bike for the collection.. This is one of mine oh that thing is killer-- MM you And brock nailed it on this BIKE>>whew i bet that thing would just be killer on a road racing track

Such a good looking machine😍

Love it bro

Gixer sounds sweet but the exhaust style isn’t very flattering against that beautiful machine.

Velocity stack and air cleaner - with the Exhaust and ECU Flash would be awesome

Wow, pretty close as my k6 750. She has full akrapovic and 135hp. Greets from finland!

I talked to Brocks about a year ago I honestly wanted to buy there system but hanging the pipe up that high vs down low like most other models would clean the look up and I bet you would sell more or maybe a option for shorter version yk

Great engine Sound perfect ✌️ Suzuki my favorite

I like it , sounds good

Nice videos, but you should get a eddy brake for that dyno, or a dyno with brake. Better and faster test and mapping. Even better videos😊🏍

CHRIS ive been waiting to see a new GSXR750 on the dyno bc i need to ship you my ECU soon!! Bout to start the vid now - i always comment right in the beginning lol 💪🏼🙌🏼👍🏼

This is 💪💪💪 my 23 750 made 134hp as well. Wonder if Chris be able to fine tune it and get more power of it ? Living in Cali that would be a far as drive but it would be nice !

Sounds great

Just got Dyno tuned last Friday, Bumped to - 124.28 HP 55.36 TQ Struggling to afford the cosmetic bits 🤣 But she rides A little spooky but feels solid

Nice brother love it

Great looking bike

Chris which bike would you buy the suzuki gsxr-1000 or gsxr-1000r? Love to hear your opinion on this matter since those are the bikes I am looking at to buy, unless you think the new busa is worth the buy spot.

Excellent bike!! but jus a simple M4 shorty cat delete wud be great..

how much did the bike weigh after putting a different exhaust on and what was a horsepower ratio from weight you know from horsepower to wait compared to a thousand with the header on that's all great job love you

I'm saving up for the brocks aswell as an e85 tune 👌 bouta be a fast boy

Sounds good

Often wondered with your mail in tune..I know your tuning with a bike on a dyno but on a mail in are you able to extrapolate the f/a via another source in ecu setting to fine tune a tune..Not every zx10 or gsxr 1000 ect ect will get their best just with flash.. I have the woolich on my gen3 zx10 and i need to learn about these timeing tweeks..Suggestions?

shows how well the factorys do engineer these bikes stock......even while restricting them and trying to satisfy EPA its not easy or cheap to improve them

Awesome video, incredible exhaust sound! That headlight is massive, time for LED’s Suzuki!

Man I love that motorcycle I don't see why in the world anyone would want anything over a 750 for the street I think that bike tops out in stock form 186 mph

I've owned 3 Gixxer 750's and loved every one of them. The last one had a full M4 system and flash and would keep up with liter bikes till around 100mph. They will always be my favorite bike.

Wow, crazy loud.

Dude you bout to make me go and get another sport bike. I don’t need that shit right now haha.

Would you be able to help me with a tune on my Land speed GSXR100 K1 engined ex top fuel drag bike? Stock engine and airboxfor the moment,but custom exhaust. UK based.

Sounds amazing would be interesting to see what numbers it would pull at the strip

Didn't think anybody still made 750 sport bikes. Neat.

Have mufflers gotten louder and louder and louder since about the late 90's and early 2000's classic round or oval open-throat style systems?

If you do a cat delete on a 750 and add a power commander is it necessary to do an ecu flash to avoid engine damage?

Beautiful

I got full M4 only reason I didn’t buy Brocks was cause it’s a high mount not low like every other bike gets from Brocks 😭

My gues: 122 after new system I think it should loose power first 133-135whp after tune... Hmmm exhup removal has to be fixed.. I had a big deep... After exhaust change.

What's your top choice for exhaust system

Hey Chris will a factory Gen 2 Hayabusa motor handle a simple bolt on 50 shot of Nitrous without doing other mods without damaging the motor?? I know it’s a diff bike but I know you know these bikes.

I have a 2020. I believe its the same bike im.going to buy brocks alien head full exhaust, but im ganna all that that you did bur wirh a Sprint p08 filter how much would thay cost for the ecu to be fladh the way you have just done to this 21?

My dream bike😭

Lol the trolling spy vs CM$

Where are you located because I see budds creek in the beginning lol

What would a service like this cost including the flash?

Bad-ass bro!

Chain still looks a little loose. Love the videos keep them coming

Does ECU flash voids the factory warranty ?

I got a GSXR 750 You tuned and flashed I bought it from Cycles Plus in Garner North Carolina y’all did the tuneup and flashed the ECU it’s a orange bike now It was a 2014

I love my 2005 750, But that color and style Perfect. Someday - I'd love to get one of those & ride it every day

My did 132.85 whp with Gianneli. What did U install for burp sound removal?

that chain tension lol

that's my dream bike

How much does this whole mod cost if I bought my bike within the next month or two and where are you located? I also want to add some mods for trick riding. I live in Las Vegas.

I've never had a new bike but it seems like by what you're saying a break in isn't required?

I'm thinking about purchasing a GSXR 750 how much do you think is possible Chris with a full yoshimura exhaust, ECM flash and some carbon smith velocity stacks. I'm in Tucson, Arizona but if i can find a bike I like I'd take it down to S.C. for some massaging.

Great work but why is brand new bike leaving the showroom with old cheap rubber?

Amazing

It scared me and I almost sound like a GSXR 1000 I love Brock's performance

Hey cris I’m the 10year old that is coming in March 4th for spectating your drag class can’t wait to be there

Any “good” stuff from you for FJR1300 second gen ?

Yeah I love it but I’m 1000 and up fan

Gsxr without a Yoshi can is sacrilege...😢 If you want more noise, just get an end can, if you want more power, just buy a gsxr thou...my opinion. Chris...love the content...👍👍👍👍

Recipe to keep my 2k Gixxer 750 with full Race Fit Exhaust and Nitron race shocks ...

Im a newbie in bigbikes, how come you can shift gears (9:28) without pressing the clutch? Is that a special features in bigbikes?

Whats the staff for deccel pop?

I got 2020 750 I need that gurgle and popping 😂

Was this with a sprint filter?

If the horsepower is like this gsxr at wheel how much horsepower in engine?

What about brake in time ?

The M4. Full that you did made 134 just like the Brock’s

Gsxr 750 is one of its kind 👌

Dang that VP oil is $15+ a quart! What's wrong with Ecstar?

Well... so much for the break in period

I did 133 on dyno on your flash. I feel like if you dynoed it we could get 135 plus. It's real real close now but some fine tuning I know you could get 135
