I have a aprilia sr50 LQ 2001
it has malossi 5gram rollers
a gianelli exhaust and is fully derestricted
it only hits 45 max
what are the best parts to get it to about 60?
and if i change to higher weight rollers will it be quicker top end?

when a bike has a stock cylinder u tend to use heaver rollers to get to higher speeds unlike a race bike which would use lighter rollers for the powerband and leave the transmission to deal with the top speed.

Try some 6.5g or 7g rollers
