Does anyone know for sure the rear sprocket number for 2014 Fz6r….looking to get a 40 tooth,for the highway
i have looked everywhere,it may be 245…JT s catalog is no help,and Amazon says nothing fits your bike…lol

thanks in advance,Bob

Looks like I found it by cross referencing actual measurements..150mm holes,130 hub…Same as FZR600…but ver few zyamahas use this sprocket
most are 130 holes,110 hub…got the last 40 tooth at Dennis kirk

I went 1 up in the countershaft sprocket with mine. 1 up in the front is equal to down 3 in the rear. I also got a 45 tooth (instead of the 46) from JT. The number is JTR245-3-45. Doing it this way the chain was still the right length.

Interesting…I called JT today and they said they only make 15/16, and 46 in back


No other choices according to the person who I talked to.

The 45 is listed to be for an NX650 Honda. The front isn't listed as available on the JT site but I found you can get both on Amazon. With the 17 on the front and 46 on the back the axle was about as far forward as it could get with the stock length chain. Putting the 45 on made it perfect. Here's some links. https://www.amazon.com/JT-Sprockets-JTR245-3-45-Sprocket/dp/B001AVOM70 and https://www.amazon.com/JT-Sprockets...Fjz9MuSGAvZFjrEdYIu2KSTs19pmTRJRoCno8QAvD_BwE

I'm interested on where the axle winds up along with the rpm @ an Actual 60 mph. The way mine is, the bike is still buzzy at 70+.
