This is a brand new 50cc 2-stroke moped scooter or utility engine. It's complete with everything you see. Gearbox and clutch built-in, please be attentive of the bolt pattern on the bottom in the picture for mounting purposes on your bike. Post starts and runs on the first try. It won't mount to my motorized bicycle frame. Firm at $75 paid $125. Cash only and you must pick up.
