whats the stock rear sprocket size on an F4? i'm at work & can't look it up

 

isnt the front stock 16 also?

 

its 46 thx guys

 

It should be 16/ 45... thats what my stock gearing was at least.

 

r u serious? opps I did -1/+4 =D. Yeaaaaah wheeleeees

 

Going -1 in the front is like +3 in the rear. You have effectively made your bike +7 on the rear sprocket. Wheelies may be easier to bring up, but with the larger diameter they will probably be harder to control. Have fun.

 

stock front and 48 vortex rear. . . stands up easily but under control
