Honda spare parts prices can make your eyes water. Whats worse is one part may fit more than one bike, but be priced differently depending on which bike you have. For example, CBR600F1 front brake seals are the same as the ones on the CB350S and carried different prices. No prizes for guessing that the CBR ones were more money.... Having owned both bikes and worked on them you tend to notice identical bits.
I have also owned no less than 2 C90s, 1 CG125, an SS50, CB400T, CB400/4, CBR400R, CBR600FJ, CB350S, CD200, CB50J, CB400N. I was a dedicated Honda fan until I discovered the hidden delights of a Yamaha RS200 swiftly followed by my SRX250 and a continuous stream of other Yamahas with only one brief rude interuption by a Suzuki GSXR400RRRRSSP.
