New Tomos front sprockets for playing with the gearing on your moped.
These will fit all A3, A35, and A55 engines but some frames require the dished front sprocket. Just check your original to be sure. Stock should be 26 on most Tomos.
These are also used as the rear sprocket on Tomos Arrow!
The 31 tooth WILL NOT FIT without grinding out your cases and even then only with HPI ignitions. The 30 tooth gets really close to some ignitions as well. Anything over 27 will need case grinding. Much larger than that and you're basically grinding out enough of the case to expose the flywheel. Just keep that in mind.
