750 Sport and Paso 14T Front Sprocket

Post by q10115 »

Does anyone know where I can buy a 14T front sprocket for the 750 Sport? The 15/39 setup is just a little too lazy off the line for me and would like better acceleration. I see lots of options for the SS and Monster engines but only a 15T version of the Sport. Otherwise I'd have to get a 41T rear sprocket and a new chain.

Sorry for late reply.
Front sprocket on many Sports are different from other models, and hard to find. Easier to just get a new chain and rear sprocket. I'm running 15/43 and like it a lot.

If you know a machine shop, you can take a 14T SuperSport/748 Superbike front sprocket and machine it down to 750 Sport dimensions. Another option is 3D print one off a CAD file, using it as a template for machining. Just some options I thought could work.

The first idea would be easier. You can buy 14T front sprockets off newer Ducs and have them machined down match the 750S sprocket dimensions.
