Unlock Hidden Power: TB60 60cc Big Bore Cylinder Kit
Transform your 50cc commuter into a more capable machine with the Universal Parts TB60 Big Bore Kit. Engineered specifically for the TB50 (1DE41QMB) engine platform, this kit increases your displacement to approximately 60cc. This boost in volume provides a noticeable increase in low-end torque and mid-range acceleration, making it easier to maintain speed on hills and keep up with modern city traffic.
Technical Performance Features
- Increased 43mm Bore: Larger than the factory 41mm cylinder, this kit provides a significant bump in displacement for improved power across the entire RPM range.
- Optimized Port Timing: The cylinder casting features revised intake and exhaust ports designed to maximize the scavenging efficiency of the 2-stroke cycle.
- Precision Aluminum Piston: Includes a lightweight 43mm piston with a 10mm wrist pin, designed to reduce reciprocating mass for a smoother, higher-revving engine.
- Complete Top-End Solution: Comes ready for installation with the cylinder, piston, rings, wrist pin, and circlips—everything you need to refresh your top end.

Mechanic's Note: This is a "TB50" style kit. It will NOT fit standard Minarelli (Jog) or Morini engines. Pro Tip: When installing a Big Bore Kit, you MUST increase your Carburetor Main Jet size to account for the increased air and fuel demand. Running a big bore kit with factory jetting can lead to a lean condition and engine seizure!
