19 Tooth Front Sprocket

Fitted one to my 2010 T100 and it made a noticeable difference without any loss of power or acceleration. Dropped the revs by about 350rpm at 60mph.
Increased the accuracy of the speedo too. Before the swap it was about 8% optimistic, after the swap it was pretty much cock-on.

 

That's a +1 for the 19T for me too. Renthal do one, and it's a great, cheap and easy mod. I still look for another gear though sometimes!

 

When I first bought my '06 T100, it seemed low-geared, so bought and fitted a 19T gearbox sprocket. That improved it but not enough, so I got Sprockets Unlimited to make me a 38T rear wheel sprocket. This raised the gearing from 62.5 mph to 72.5 mph at 4000 rpm, which makes for much more relaxed touring and riding on dual carriageways and motorways, and I get 58-59 mpg when averaging 50 mph cross-country. The bike still reaches 90 mph fairly quickly and 100 mph if you really need to. The speeds quoted here are genuine, not the 70 mph and 80 mph equivalents shown by the speedomenter.

 

Hi I have 2017 bobber t120 can someone tell me if I can get hold of an 18 or 19 front sprocket it currently has a 17 t and there is plenty of room for a larger one to fit under the casing
