dont know what difference renthal will make as i put 520 light weight dp 36/14 set up on it was one of the first thing i did to my 999 as 5 & 6 gear was way to heigh as for acceleration it pulls even harder than before first gear can lead to front lifting at about 7k as for top end my speedo goes ---- when it gets to 177mph so not to many problems their either. |
