1. nice product but be careful
-Very well made
-Nice finish
-Lighter weight than stock steel spacers
-Makes installing wheels much easier
but:
-Product comes with NO INSTRUCTIONS, no illustrations, nothing.Not even on the Driven website. Brian's video is good but, as he says, each model is a little different.
On the CBR1000RR each of the four spacers has a unique shape. With no instructions or markings, it's your job to carefully match the new spacer to the original spacer's shape.
-Spacers must be removed/re-installed each time the wheels are balanced. Due to the slight play of the captive spacers within the rubbers seals, they must come out for an accurate balance. Not a big deal but your mechanic(s) needs to get everything exactly right when they re-install the spacers.(Mine installed one spacer backwards.)
-Cool product but...heads up!
