Same final ratios, so all it does is give you a closer ratio box.Stuzrx wrote:Can someone please point me in the direction of the ZRX 6 speed gearbox update.

Have a look at zzrbikes.com motors show up there from time to time.

And that there is the reason I never bothered with that mod. If it lowered the final drive I would be all over it like a fat kid on a donut...........as long as donut man was nowhere to be seenFred wrote:Same final ratios, so all it does is give you a closer ratio box.Stuzrx wrote:Can someone please point me in the direction of the ZRX 6 speed gearbox update.

Re: 6 speed 'box.
I like the 5 speed box. One less gear to change. Bike is so smooth I have found I have done long distances in 4th on the highway accidentally. 

2 X ZRX1200R 4 X ER6N, GT550, 1988 ZX-10, 4 X GPZ250R, 4 X GPZ900R and GPZ750R
Yeah I like Kawasakis.

Re: 6 speed 'box.
In conjunction with the six speed there is an option of using the top gear ratio from a GTR 1000, they apparently run a taller top gear.
You can then lower your final drive ratio if so desired, well thats what I would do if I had the money & inclination.
I have always felt 1st is too high for crawling in traffic & yeah it needs a higher top gear, you could always use 2nd to launch if the final drive was a little lower.
As another alt, I thing it was "bigtire" on ZRXOA who did a limited run of top gear cogs with even more overdrive than the GTR, I beleive he made extra's over & above pre-order qty's & did have some left over, that was some time ago (ancient history even)
