Yoshimura Axle Adjuster Blocks make swapping rear wheels easier. By replacing your bike’s OEM adjuster blocks, you’ll find adjusting the chain to proper tension after a wheel change to be much easier than before. That’s because mass-produced adjuster blocks aren’t made with the same CNC-precision that these 6061 T6 aluminum pieces are. OEM blocks have notoriously loose tolerances and consequently allow the rear axle to move ever-so-slightly in the blocks while you torque the axle nut to spec. The end result is an improperly tightened chain, sometimes even with the old screwdriver/chain tensioning trick. These blocks help reduce chain slack frustration when swapping wheels and eliminate some unsprung weight too! This is the same kind of kit used on Yoshimura Suzuki’s AMA Superbikes for the reasons we just mentioned.

Available for Yamaha 2003 - 2005 YZF-R6, and all YZF-R6S models
