Things shake off the bike often. Most damage has been caused by this. Front brake caliper lost a bolt causing the caliper to swing out and hit the PM wheel/rim causing scratches. The carbon fiber Vance and Hines pipe, which I added when I got it, literally has shaken itself to death. Nuts bolts and screws constantly need to be tightened, sometimes replaced. Only the caliper bolt resulted in danger and significant cost (had it buffed out).
Clutch cover needed a gasket at 15K miles. A throttle cable needed to be replaced. They over the top of the engine and the lube effectively dries/bakes and the inner cable rusts through. Rear brake pads die quickly, and I rarely use the rear brake... mainly because it really doesn't work much at all.
Nothing really expensive, nor major. More and more parts, however, are made of "unobtainium"... just can't find them. The 1995 is a pre-production hand-built and only 1400 were made.
Bike still looks awesome and turns heads. It is so unique it always get lookers in parking lots.
The bike sounds awesome, and turns heads. Get compliments on the sound.
The torque is amazing. I live in Colorado and it eats up the mountain roads. The 50 to 100mph roll-on is nearly super bike numbers (look it up, it is true... it eats most in-line fours in that range).
While a tad heavy, it handles fantastically well. It always starts and is easy enough to maintain. There are LOTS of go-fast options available... I have a moderate few: the aftermarket pipe, a MUST, a Screaming Eagle ignition (basically, some advance and higher rev limiter, which gives it a better sound as well).
