Ditch your soft, clapped-out stock tubes and transform your front-end tracking with the premium NCY Performance Front Fork Assembly. Engineered specifically for Yamaha Jog architectures and matching 139QMB platform variants, these high-performance stanchions feature sports-tuned internal damping rates that dramatically diminish nose-dive under heavy braking. Finished in a high-gloss silver coating, this complete leg set stabilizes your tracking through high-speed turns — ensuring a crisp, confidence-inspiring ride on both street commutes and race setups.
Advanced Suspension Features
- Sports Damping Optimization: Calibrated to deliver a stiffer, more predictable spring and rebound rate than mushy factory originals — providing better tire contact and road feedback.
- Flawless 26mm Tube Profile: Precision ground to a 26mm outer stanchion diameter, sliding perfectly into compatible stock or aftermarket triple trees.
- Disc Brake Ready Geometry: Features integrated structural mounting tabs cast directly into the lower leg to support standard hydraulic disc brake calipers.
- Complete Setup Kit: Ships as a matched pair (left and right legs) and includes two premium stainless steel hose/line clamps for a professional garage install.
