For me, the bike handles great. I haven't taken 45 mph curves at 90mph like some of the friends did when we went to the charity rally in Terlingua, Texas, near Big Bend National Park, but I feel it would if I was crazy enough to try it.
The gas tank is only 3.7 gallons. I chose to accept that because all my friends that have road machines told me I would be stopping every 100 miles anyway. Whether to get gas or not. I've gone 150 miles and still had 3/4 gallon of gas in the tank when I filled up. The tank is under the seat, which I feel adds to good handling.
Wind hurts the gas mileage though. On one trek, high wind dropped the gas mileage to 35mpg. Otherwise, it get 55mpg.
Acceleration is great. Even better than my friends Yamaha 1600's. Even though it just under 1500 cc, I kept up just fine with the bigger bikes on our rally run to Terlingua. 800 mile round trip plus what we rode while we were there. The bike climbed to 105mph with a passenger pretty quick. That's the fastest I've had it, and it seem to want to go higher.
The bike seems to want to cruise at 80mph. At 65-70mph though, the sweet sound of the motor, and the low rumble from the pipes is very relaxing. I know Cobra or other top brand pipes would increase performance, but I plan to keep the stock muffler system. For the neighbors if anything.
The clutch seemed to need adjusting for a while. I guess it just needed to break in, because it's a lot better now.
The bike shifts loud, but that is common on Suzuki from what I'm told.
The brakes were noisy, but settled down with time and miles also. The bike brakes good. I had to slow down suddenly from 65mph when it looked like a car was going to run a stop sign at a highway intersection.
Well, I hope I can add to this review as time continues to prove that Suzuki C90T is a great bike to have.
