Fit the 14T sprocket, adjust the chain & you are on your way.

woottonboy you said your top speed was 175kph now 165kph what you running on rear? im using 15/45 and top speed for me is 150kph bike is screaming so i back of to 100kph....have a rear sprocket 47 from kev which ive yet to try

pommie

gps reads sustained a 165km/h flat out
 

google earth the test strip, Coolongolook to Bulahdelah

specs: - standard 45 rear
- front 14
- engine standard
-premium juice
-rider (scared) 95kg.

over 150km/h on the XT660R is like 210 on the XJR1300.

not much longer now

That leaves one renthal sprocket $25 to your door.

No chain problems with this sprocket man. The chain won't even notice the difference but you will.

Hello.
Just 1 question about gearing down/up.
Will i have to install a speedohealer? or it wont change anything? Reason im asking is because ive heard that it DOES change the reading when changing the gearing?!?

Checked it on Sunday in mph. Speedo reads 7 mph over with 14 tooth sprocket on. You could fit a sat-nav to check your speed .

With 14th driving the standard rear you will be reading higher than you are actually doing.

Tried it at the weekend with the speed 'warning signs' before the entrance to a local village - you know the smiley/frowny face ones.

Doing 60 on the clock I was actually doing 54mph according to the face.
Doing 40 on the clock I was actually doing 33mph

However if you do the maths at 60 you would really be doing 56 and at 40, 37mph.

So the camera probably got me before I had reached a steady speed.

I personally will not be fitting a healer as its the right side of the law.

Alright, thanks alot.
Guess ill just have to get used new readings then. :) Might buy a speedohealer later for proper reading.

Personally, from my own experience I did put a 14T front sprocket on when I first started a bit of trail riding on the Ten. But I found that this hooked quite quickly, but then I was riding in very aggresive and dirty conditions.
I did find that when I went back to a 15T front I also had a bit more confidence and didn't notice the difference as I was riding faster on rough ground.

From my last little episode I would always stick to the 15T front as when my chain snapped there was certainly quite a bit of chafing on the steel plate that runs over the chain on the engine casing. I'm sure this has prevented any damage to the casing there.
If I was to change the gearing I would certainly get a 48T rear sprocket (I do have a 46 spare from somewhere in any case?), this I believe would also give the chain an easier life as it runs over the drive sprocket with it being a bigger diameter.

Hope this makes sense, if it's a crock of poo then I'll get my coat!!!!!:034:
