Aprilia rs 50 Pro Race Tuning Part II Sound 70cc 

It’s based on your tuning in your carb having a 70 kit or a 50 kit will wake no difference and the more smoke the betta not to much tho but a 2 stroke should always smoke

Probably using pre mix in the tank, you can get green 2 stroke oil as well doesn't smoke as much and the bike rips. Any big bore kits don't add much tho it still has the same gearbox

4t slow and bad

@@hunvalorant-i7i sounds way better and runs better

because its not the original exhaust🤦

Elias I thought only the rs4 50cc could have side exhausts like mine, my friend who has an rs 50 like this could only find undertail exhausts for it, so he got a undertail arrow exhaust, didn’t know if this guy fitted one for the rs4 50 or not.

Stock they have it under the tail but aftermarket they only have like 3 exhausts that come out under its tail and they are expensive

And i'm gonna buy one😂 it looks sick if it comes out the rear end

mattia chiaramonti it‘s metrakit 70cc pro race 2
