AP Workshops - Aprilia V4 Engine Casing Problems ! 

These guys absolutely 1st class...can't recommend them enough to anybody considering taking their bike to them! What this fella doesn't know about aprilias probably isn't worth knowing! Thanks again mate Griff and those covers are trick AF

So glad you told us about this I took mine off today and will be ordering some covers off your website. Cheers mate keep it up legend.

Any V4 owners that want me to take your bike out and actually ride it after you have washed the garage queen to dry this cover, please feel free to get in touch 😀

Take the cover of and spray ACF50 or similar on the alloy cases this will help.

For anyone interested check under this cover. I have a tuono with 1000km on it and engine case was starting to get damaged with the wet foam. My advice is either buy gb covers or simply remove the foam from inside the original cover to stop water lodging in it. No difference in sound deadening

Another excellent vid. Any chance we can get those torque figures please?

Fitted my GB Racing covers yesterday on my 19factory, no marks on the casings but the foam in the standard ones was soaking wet. I tend to wash my bike then put it away in the garage, but even with a dryer it wouldn't dry the foam. I also removed the redundant stand-off fixings and replaced with cap heads to keep it looking tidy.

Thanks for the heads up. FYI, my understanding is our RSV4s casing covers exist to suppress engine/trans sounds and that’s it. Aprilia didn't fit them for casing protection, at least I didn't see that stated is their purpose. In all reality, we should remove those and replace them with effective covers. I’m in the states and installed a different manufacturers product.

great advice there, I swear by those GB racing covers, really saved my bacon in 3 huge crashes

The factory cover is just a sound deadener that retains crud. You need Yakety Sax for the sound track.

Interesting that GB Racing cover protects only the most exposed part so is good for a tarmac grind. However the other case protects the whole side of the engine which makes it effective against a gravel trap incident..

Brilliant thank you ✨👍🏻

It's a shame the GB Racing covers don't come without that ugly writing on the side.

Is this applicable to the later 21/22 models? They seem to be a similar looking cover

Couldn't you just take the foam off?🤷‍♂️

I just found your channel thanks. (subscribed)

Good lord, ill be yeeting these asap.

Do you have to take all bolts off to get the stock foam cover off?

The benny hill music would have been so funny :)

Where you guys get the frame covers in Matt ?

Happened with me , purchased motorcycle from dealership & the clutch cover has deteriorated down to the bare metal - new case needed

I've got a Miller gen 1 put it's sounds like it's misfiring because it judder when pulling of

I recently ordered carbon covers for my bike. Still waiting for the clutch cover but did receive the alternator one. They are delivered without the foam. At first I swapped the OEM cover with the carbon one without using the foam, only to notice that the engine noise increased a lot…. I ended up pealing the foam from the old cover and using it to fit the new one… the foam has a sound dampening purpose. I’m pretty sure that clutch will be a lot noisier after you’ve fitted that R&G cover…

It might just be worth removing, and not putting any engine cover on. None of my other bikes have an engine cover, and it looks like it's mainly for sound deadening...

Out of stock on your website!!

Why don't just remove the foam?

i hear that actually riding the bike would solve the issue

Damn v fours

Italians...... nuff said.

Couldn’t you just take the foam out?

The static transitions effect sounds terrible on headphones. please stop using them
