There is no fuel gauge, however a "fuel low" light is present, which gets brighter as you approach the reserve. Filling up at the lowest brightness of the light will result in only half the fuel capacity of the motorcycle being used. The bike has a 4 litre reserve, switched to with the usual fuel cock on the left hand seat unit fairing.
The larger two engine sizes are under-stressed, and as such many have been known to go on for up to 80,000 miles with no significant engine work.
The 400cc version is somewhat different, and uses the 400cc powerplant from the Suzuki GSF400. As such it has 32mm Mikuni carbs instead.
All the bikes use steel 4-1 headers. The later 600, and all the 900 versions use a tri bolt can fitment. As such, any Suzuki GSF1200, Kawasaki ZX9R, Suzuki GSX760R SRAD, or Triumph TT900 tri bolt can with strap based mounting system can be used. The earlier 600 and all 400 RFs use a slip on with link pipe system, with a join below the center of the bike.
High Flow filters are available, and provide the advantage of a cleanable element. Combining a jet kit, a free flowing exhaust can, a high flow filter, and GSX750R cams with a 7 degree ignition advance can produce up to 160hp from the 937cc engine.
The pink wire connected to the ECU of some of the later 900 bikes retards the ignition timing in the lower 3 gears to make the bike more user friendly, limiting the ability to spin up the rear wheel out of corners, and reduced wheelie tendencies. Disconnecting this pink wire removes this feature.
Braking is good from the stock Nissin brakes, however the 900 can be fitted with Tokico Hayabusa 6pot calipers using the standard mounts, and with braided hoses, this modification provides phenomenal stopping power, at the expense of some braking feel.
Sintered pads are not recommended as they tend to excessively wear the discs.
