1. Info - Roaring Toyz 330 Wide Tire Swingarm Kits
The Roaring Toyz 330 Extended Outside Drive O.S.D. Swingarm Wide Tire Conversion Kit is the Ultimate Custom Modification for your Sportbike today. This Roaring Toyz Sportbike Fat Tire Rear End Conversion Kit is a true Bolt-On kit that requires no cutting, grinding or welding. The unique Outside Drive design allows for a centered 17x12" custom rear wheel without the use of a jackshaft. These swingarms are engineered not only for awesome looks but to be 100% functional as well.

The O.S.D. is the best wide tire technology available for wide tire kits. The kit uses a wide offset front sprocket made from 8620 steel and heat treated to run a single chain from the countershaft sprocket to the rear sprocket. The front sprocket is supported by a outboard bearing housed in a very trick CNC machined 6061 billet aluminum cover that is bolted down to the engine cases and the frame for rigidity. This bulletproof design emulates car tire dragbike set ups from the last 3 decades and not only adds strength and function but looks insane too! This new wide tire technology eliminating the jackshafts previously used on 300 & 330 wide tire set ups adds huge advantages such as higher performance thru more power delivered to the rear wheel, better handling, smoother on/off throttle transitions, less parts to wear and break, easier maintenance and wheelbase lengths from 0-18" over stock.

Roaring Toyz Custom Wide Tire Swingarms are built in house, using only the highest quality materials and precision CNC parts
