Well Spyder Owners....
MMG is proud to announce the FIRST AND ONLY
30 tooth Billet Aluminum Front Sprocket
Not only is this sprocket lighter, it reduces you 400 RPM's and increases gas mileage!!!
CNC machined from 6061 Aluminum
This is a direct replacement for the factory sprocket and still uses the stock drive belt!!!
29 tooth:

Microsoft Office Excel Worksheet is available with the comparison between stock 28t and MMG29t

I bought one of MMG sprocket 29 tooth last summer and I didn't have to replace the belt. Just loosen the rear wheel and move it forward to allow for slack. The sprocket was very easy to remove and extremely easy to install the new one. I figure I have close to 8,000 miles using it and it does drop the rpms about 400. Someone said that using this will make me slower on the take off and it does. Instead of doing the 1/4 mile in 10 secs (I'm just picking a number I don't know for sure) it takes me 11 secs. It has improved my gas mileage enough that it is noticable on a trip. I can probably drive and extra 30 minutes before needing to gas up. If you want to go faster on the start then this isn't for you but if you want lower rpms in the higher gears and better gas mileage then this works for me.
