Yamaha YFZ450R 2009-2017, Suspension Linkage by GT Thunder®. Custom sport quads suffer from leverage ratio curves that are too aggressive, causing a spike in the suspension as the quad gets further down into the suspension travel, which results in a harsh ride when ridden in rough terrain.
- Patented suspension linkages
- Gain additional wheel travel by using improved leverage ratios
- Plusher ride while still maintaining good bottoming resistance
- Lower center of gravity
- Improved stability for better overall handling
GT Thunder® developed a few different linkages for some common applications. These linkages are not designed to raise or lower you bike as much as simply giving you the correct amount of travel and the correct location of that travel.
