Motocross Gearbox Dual Sport Kyb

Motocross gearboxes are engineered for abuse. Close ratios keep the engine in its powerband through technical sections, while robust internals handle the shock loads of landing jumps and powering through whoops. This racing heritage translates directly to trail performance when you need quick shifts without thinking.

Dual-sport conversions often retain race-derived transmission components. The close ratios that work on tracks also help navigate tight single-track where momentum is critical. However, highway cruising suffers without taller gearing—most dual-sport riders compromise by installing larger countershaft sprockets for improved top-end comfort.

KYB supplies suspension components to multiple motocross manufacturers as original equipment. Their closed-cartridge fork design provides consistent damping regardless of bike attitude. This means predictable response whether accelerating out of corners, floating through whoops, or landing from jumps.

Revalving KYB components opens significant performance potential. Stock valving compromises for rider weight ranges and skill levels. Custom valve stacks tuned to your specific needs dramatically improve control. Professional suspension tuners can transform stock KYB forks into components rivaling far more expensive aftermarket options.

Transmission oil selection matters for shift quality. Racing-specific oils reduce friction between gears, making shifts quicker and smoother. Synthetic formulations maintain viscosity across temperature ranges. Change intervals should be shorter than engine oil—transmission components generate significant heat and contamination from normal wear.
