RFX Pro Chain Tensioners (Blue) — machined axle blocks for the demanding rider. Designed for motocross terrain, these RFX Pro tensioners provide precise and repeatable adjustment of chain tension and rear wheel alignment, eliminating guesswork during adjustments.
The blocks are CNC machined for high precision, making it easier to align the axle and set the chain, even after a wheel spin or muddy outing. Their profile allows for stable positioning on the axle and easy access during adjustments on the track or during maintenance. Sold in pairs, they naturally fit into the routine maintenance of the rear end of off-road machines.
Compatibility: primarily intended for motocross — among others, suitable for YAMAHA YZ 450 F (CJ10) 2008, YZ 250 F (CG27) 2008, and YZ 250 (CG23) 2008 models. Check compatibility with your model before installation.
