Ya on here right now eh Steve

THat's it my man you have to throw 'em a bone very now and then
so they "remember" you when you need the big stuff taken care of.

 

if ur goal to get 310 km top speed then use 13 teeth front and the biggest sprocket on rear but the only thing that u can not get more power in the first to 2nd gear but when u reach the 3th to 6th gear , u can feel the differences, its like u have nitro in ur bike... this is not good for short drag racing..

 

Raiden

Actually I think you mean

as big as you can go on the front ......which is 18
and as small as you can go on the rear ........which last I found was 38
(Smaller rear sure but you'll start sawing off your swingarm)

Makes for greatest TOP END speed.

Actually ..........it's a fact. Here's the JT Sprocket Gear Ratio Chart Attached

 

if that ur experiences then i don't wanna argue with u, just show me the proof if ur cane can reach over 300 km because am gonna changes mine too but if not then am gonna follow my experiences..

 

With respect, Raiden,you have the ratios backwards.........
bigger front and smaller rear sprocket gives you higher top speed, but less accelleration. Your 13 front would make the bike unrideable, (and I don't think it would fit anyway, as the chain angle would be too abrupt. I've dropped mine to a 15 front, and the bike became a wheelie machine) 15/46 is enough to drop GSX1000R's on accelleration.............but the top end drops down to about 200KPH
As for 300, I can vouch for 265 with 17/42 gearing, and I still had about 20 K's per hour left, so I guess under the right conditions, 300 would be possible, but you'd need lots of room................

 

mine is different style shadow, 13/52 came from dirt bike sprocket but need to modify..

 

No need to argue as Shadow says, and the chart demonstrates
Bigger up front , smaller on the rear for greater top end speed

Run an 18/39 and mod the motor for NOS

300 will be a starting point !
