I know about Sab/Mags I was a member when I had my Sabre. I still ride with Doug and Jim once and a while. I was the guy with Jim when he had his get off a couple years ago. Anyway that doesn't have much to do with Bandits. I've had my '02 bandit for 2 1/2 years and put 36,000 miles on it. Your right the suspension on the Bandit is off the shelf and could use some improvements. The locking feeling you get is exactly right, the holes in the stock front fork valves are too small and the spring too strong so when the front end gets a good jolt it does hydrolic lock up. RacTec Gold valves have bigger holes and a multi rate leaf spring so they work better over a wider range of inputs. Bikes like the Sabre have a damping rod type front shock where the damping is controled by the viscosity of the oil. A popular upgrade to the damping rod type fork is to install "cartridge emulators". The Bandit has a cartridge type front suspension so doesn't need to be "emulated". I installed both the Race Tec Springs and Gold Valves in the front and adjusted the rear to my likeing. If that doesn't give you what you want then there are lots of aftermarket options for rear shocks Oilins, Penskie, and GP supension comes to mind. You might look at the Race Tec web site, there is a ton of information on it.
