Just thought I'd say how pleased I am with the suspension upgrade on my VFR1200F. I've fitted a Nitron R1 shock, K Tech linear springs and their Piston Kit to the forks. Total cost including labour (I fitted the shock) was £820. Bike feels like it's lost 30kg, turns in SO much quicker and I'd FAR more stable. Not much out there on the Piston Kit but they make an incredible difference.
