I'd like to push my Gilera DNA125 a little (acceleration + top speed)
To start I was thinking about placing a Malossi Multivar. In the description it says 'better acceleration, better top speed'. Does this vario really make a difference in top speed? Is it useful to add the Malossi kevlar belt?
Next I was thinking about a Scorpion exhaust, though for the same money you have a 210cc bore kit... When applying that 210cc kit, do you need to change some other stuff too? (carburettor, ... )
