Pro Jet Sports 25mm Oversized Throttle Cable Drum ? The Only 25 mm Drum on Earth
Born from the need to retain factory oil-injection timing-cover setups while giving riders the mechanical advantage only a larger radius can deliver, the Pro Jet Sports 25 mm drum is still the one-and-only oversized drum available anywhere. Blue anodized 6061-T6 billet, laser-etched with the Pro Jet Sports logo, part number, and specs so you know it came straight from our California CNC facility.
Features the same bulletproof ?D? hole lock as our legendary 18 mm drum, but the 25 mm diameter multiplies every ounce of finger input ? perfect for big-carb triples, high-compression engines, or anyone who wants smoother progression and less fatigue on long motos. Racers quickly discovered the extra leverage works magic on non-oil-injection builds too.
- Exclusive 25 mm diameter ? unmatched leverage
- ?D? hole locks to throttle & oil pump shafts
- Blue anodized + laser-etched branding
- Multiple cable positions for fine tuning
- Made in USA ? the original, still the only
When standard drums leave you wanting more feel and control, step up to the drum that exists because Pro Jet Sports refuses to follow the crowd.
