I purchased one on my 2013 F6B and have used it twice. Once for the fork seals. One of them leaked one year and mother honda repaired free of charge, and the amp went maybe the third year and mother honda replaced that also. The amp was a costly repair. If it had not been covered the whole system would have been scrapped for something else. she has been fine other than those two minor repairs. Like some one said earlier if I never used it it would be the most well spent money on the planet. I would not purchase two wheels with out one. Its risky even with the most reliable machine on the planet.
