Poor information on Yamaha's Website. Cat's is way more informative for Viper

Depends on the model. Vipers were always 24/50 except for the XTX at 21/41, but in 2015 the LE model Vipers got 21/49 gearing.

Do know What are the gears are of the S tx dx 146 track?

Funny most if not all the magazine reviews disagree with you...the clutches on the 7000 are perfect. Ultra smooth, just the right amount of engine braking and belt life isnt a issue[/QUOTE

Ya and we all know the mags are always right and honest. Lol

If your happy with the cat clutches i think thats great but a lot of the Reading i have done in the cat forums. Claim the new cluches are almost impossible to service and there is a lot of them wearing out premarurely.
Lots of guys claim they are Made out of cheap chinese junk.

If you are happy with yours thats great. Just not my cup of tea
