History
Specifications
The SR4 would have largely similar motors to its larger siblings, with one notable exception; the 998 cc (60.9 cu in; 0.998 L) Honda CBR1000RR motor, which was one of the unique options to the SR4, with only 7 being produced with this engine, and only 2 retaining this engine as of December 2024.[3] The other unique engine option was that of the 1,164 cc (71.0 cu in; 1.164 L) Kawasaki ZZ-R1200, which was the first engine fitted to the car, but no car built with this engine is still fitted with it as of December of 2024.[1] The 1200 will do 0-100 km/h (62 mph) in 3.7s, the quarter mile in 12.4s and has a top speed of 234 km/h (145 mph).[4]
