Rear sprocket.

Fitted a 44t supersprox sprocket. Help the front stay down and make the gears a little longer.

After only just trying it out properly, I must say it was a great improvement. Smoothed out at low speeds less jurk. And the longer gearing is so much better.

Did the same mod on mine in july. Supersprocket 44t - Black/Gold.
Much easier to put the power down to forward momentum (It still wheelies easy enough)  :001:

I wonder if with this 44t sprocket, the 6th gear will reach the maximum speed? Is the maximum available top speed increasing?

Has anyone measured it with a gps?

Seeing as how max speed is reached right at redline in 6th, this sprocket mod will lower the rpms at the same speed at the top of 6th gear. Peak power is not at redline. We have a heavily restricted ecu after 10200rpms. My guess would be top speed will actually increase.

Does this sprocket change make the gearing higher or lower? If it lowers the gearing then surely the theoretical top speed would be lower and the opposite if the gearing is higher......

It is often confusing to use words like higher and lower. Some tend to interpret/use them opposite regarding gearing.
Regardless of your interpretation, more teeth in the front and less teeth in the rear (like here 46->44) will make each gear "longer". That is.. at redline you will have a higher speed, hence a theoretical higher top speed in 6th (for "our" bike also in practice as it it will travel faster at the rpm when the ECU start closing the butterflies).

So, that means this mod will give the bike more m.p.h. per 1000 r.p.m.   Does anyone know  how many m.p.h. per 1000 r.p.m. the standard gearing will give?
