Front sprocket question
 

I've done a search and read the threads about gearing. My bike came with a 16 front sprocket but the dealer I got it off also gave me a 15 sprocket. Is it worth it and will I notice that much difference if I change it. Is it going to be a night and day difference or is it marginal.

It all depends on where you ride, a 15 tooth is better for twisty roads, a 16 tooth is better for freeway cruising.

With a 16 tooth sprocket the speedo will be reading incorrectly.:icon_salut:

Did you buy it new ???

I did a fair bit of work on the Tenere gearing last year, have a look at

There's a lot of guff about fitting a speedo healer but the content is fairly explanatory.

The standard is a 15 and comes with a speedo error of about 8-10%.
A 16 will bring it more into line but it will throw the odometer out. The odometer is fairly accurate with a 15t.

On top of that you may find that it goes faster in 4th than 5th especially loaded or with a head wind or slight incline. (with the 16t)

As Kev said, it also makes a lot of difference as to how you want to use the bike. I currently have a 14t on the front and it make off road and traffic driving a lot better, but I fitted the speedo healer to bring it back to the original error of 8-9%.
