    Complete 25mm Belt Drive and Clutch for your Triumph Pre-Unit 650 swingarm motorcycle. This belt drive fits inside your stock inner and outer primary on generator-equipped, swingarm-frame bikes only. If you have an alternator-equipped, swingarm pre-unit Triumph the outer primary over needs to be spaced out slightly using a custom spacer (not included).

    Bob Newby Racing produces the highest-quality, no-hassle belt drive and clutch available for vintage British motorcycles. This kit includes everything you need to replace your stock primary drive and clutch. The front engine pulley is one-piece, hard-anodized aluminum and fits right onto your stock crankshaft splines. The hard-anodized aluminum clutch basket features nclosed bearings, no hassles with installing loose ball bearings, it slips right onto your transmission mainshaft the same as a stock clutch hub center. New steel and fiber clutch plates are included, as is a 6-spring pressure plate and hardware, and a Gates HTD 880/8M length 25mm belt capable of handling much more power than stock and able to be adjusted with more finesse. No more adjusting a primary chain, checking your chaincase oil or trying to fix primary drips with the Gates HTD Belt and your new dry primary.

    Here at Lowbrow Customs we are big fans of the Newby Belt Drive. They are race-proven on three land speed motorcycles here at the shop, with a total of six world land speed records having been set at various SCTA events including Bonneville Speed Week and Bonneville World Finals. All of the power driven to the rear wheel runs through the Bob Newby Belt Drive, and we have never had a single issue with the clutch nor ever broken a belt!
