Complete Transmission Assemblies Built for Torque, Control, and Longevity
Choosing a motorcycle transmission replacement is about solving real riding problems, not chasing specs. A properly engineered complete motorcycle transmission setup restores smooth power delivery, reduces cruising RPM, and eliminates weak factory tolerances. Options offered by TMF Cycles like the Baker Direct Drive 6 Speed fit directly into existing five-speed cases, adding a sixth gear while lowering highway RPM. Its polished trap door, helical upper gears, and included sprocket and chain components show how a true Harley transmission assembly should arrive, complete, balanced, and ready for real miles.
More advanced builds demand tighter ratios and higher strength. The Baker Direct Drive 7-Speed replaces factory Cruise Drive units without case modifications, using a lightweight mainshaft design to reduce shift clunk while managing torque from larger displacement motors. For aggressive riding, the Baker Grudge Box delivers a heavy-duty transmission unit engineered for high horsepower abuse, with straight-cut gears, wider profiles, and a bulletproof bearing system. These Harley complete transmissions and V-Twin complete transmissions arrive as fully assembled motorcycle transmission solutions, combining gears, bearings, and shifting systems into a single full motorcycle gearbox assembly. Whether upgrading touring comfort or managing extreme power, these aftermarket motorcycle transmission assemblies provide a complete V-Twin transmission unit with an integrated shift drum and gears assembly and reinforced motorcycle transmission bearings for long-term durability.
FAQs
What makes a complete transmission better than rebuilding stock units?
Complete assemblies arrive fully engineered, eliminating compatibility issues while improving gear strength, bearing support, and shifting precision without trial-and-error fitting.
Do these transmissions require engine case modifications?
No. Baker's six-speed and seven-speed units are designed to install into existing cases without machining or shimming.
How do wider gears improve durability?
Wider gear profiles spread load across more surface area, reducing stress, heat, and long-term wear under high torque conditions.
Are these transmissions suitable for high-horsepower engines?
Yes. Units like the Grudge Box are specifically engineered for aggressive launches, sustained speed, and high-output Harley performance builds.
