The Ultimate Honda 650/680/700 Gear Reduction is built for riders who need a serious gearing upgrade for larger tires, deep mud, and demanding off-road conditions.
- Custom forged gear set providing 47% more torque
- Ultra-smooth tooth profile and gear mesh for quiet operation and efficient torque transfer
- Chromoly forged and heat-treated gear set engineered for increased strength and long-term performance.
Fitment:
Fits Honda 650, 680, and 700 4x4 ATVs, including Rincon and Rubicon 700 models.
These gears are not recommended for the Pioneer 700 UTV. These gears would result in a smaller reduction in the UTV and require additional mods in that transmission.
Important Fitment Note:
These gears install in the rear of the ATV engine. Professional installation is required. Installation requires very slight clearancing of the transmission case, with less than 1mm of case material removed to fit the larger output gear. This can be achieved using a polishing tool or burr. We do not recommend using auto shift mode with the reduction installed.
