Yesterday we replaced the stock front suspension components with new seals, valves, piston and springs from K-Tech. I needed to upgrade as I weigh in at 225 lbs. A fellow by the name of Chris at K-Tech U.K. was very helpful in sourcing the correct kit for us here stateside. It seems I now am on Ducati fork springs and some Jap bike bits. The bike is transformed and is finally a joy to ride on bumps and through twisty back roads. I am getting a custom spring done to fit on the rear shock. Just proves there are great fixes that don't force you to spend an arm and a leg with Ohlins. If any of you "big" riders want part numbers just PM me and I'll forward the email from K-Tech with parts information. We did have to trim 24mm from the rod to get proper spring to valve seat feel. Whole job took 4.5 hours. K-Tech is awesome!! CHEERS, Chris
K-Tech did a full front fork job on my GSXR 1000 K6. They did a brilliant job On my current S3, I was looking to do the same but then I had the std suspension tuned in professionally. I weigh 75Kgs with the gear. Seems good with handling. Sometimes I think it's a little on the hard side through bumpy roads, so I changed tire pressure to F32 R40 and all seems good.
Try lowering that rear tire pressure to 36, it does wonders for the harshness. This was suggested to me by a pro AMA racer and it works real well. EDIT to add - behaves spot on stable at speed, I detect no handling changes other than a less harsh ride on the bumps.
