Gearing for EC

[Leezx10r]

After fitting 200/60 rear tyre to my zx10r it really had a big effect on my gearing.
Did a few checks and looks like the calculated top speed at 13k RPM is 290kph.

Current gearing is: 16f / 40r = 290kph

Thinking about: 16f / 44r = 265kph

Any thoughts?

Easier to drop one tooth down the front.

Sure is Chubb, but don't want to make the radius any tighter on the front

I run a 14t on the front no dramas.

No tight spots or anything in the chain. Which is now a year old so due for replacement.

Plus going 4 teeth in the rear plus a 200 tyre you got to take into account the space between the swingarm and the tyre. You do have enough clearance?

Thanks Chubb, 14f 40r is giving me 256kph

Could buy a few a try different ratios

And a new, longer, chain (or several extra rivet links). That many more teeth is a LOT of extra chain....
