I recently had to replace the chain and sprockets on my '06 CBR600 F4i. I bought an RK setup and a simple circuit breaker. Everything worked fine on my first attempt at installation, but I damaged (bent) one of the breaker contacts. I wasn't worried because I managed to rivet the chain. BUT I had to build another bike of mine and we have a problem in Houston. 525 and I bent/broke all the pins that came with the kit. So now I'm stuck on the bike and I'm faced with a dilemma: I can either get a cheap chopper set from CycleGear or order a Motion Pro. I read reviews and I always read negative ones to see the complexity of the item. I decided to pull the trigger and make a purchase. I am very happy that this switch is worth every penny. Not only was it easy to use, the rivets I made looked professional. I didn't even bother to rivet because the instructions were very easy. Definitely a tool that will last for many years.
