Koichi Fukaya's bike featured Showa works suspension, out back it had the BFRC (Balance Free Rear-Cushion) shock. We've talked about this shock multiple times before, being that the layout is different from a standard shock..with all the valving lying behind the adjuster with no shim stack on the piston on the shock shaft. We've heard a few manufacturers have tested production versions of this shock for the past two years, but we might finally see it hit a production bike this next year...
