To gain a strategic position in the premium segment, Bajaj engineers replaced the Kawasaki engine with underpowered, 178.6 cc DTS-i engine from the Bajaj Pulsar sportbike. However, the engine had to be re-tuned to suit the torque-demanding characteristics of a cruiser. The bike was launched in June 10, 2005.[1] It is also the first cruiser developed by an Indian company. The wheelbase is 1, 475 mm(58.1 in). Mileage around 45 kmp lThe Avenger was upgraded in 2007 with an increase in engine capacity to 200 cc. The oil-cooled engine was a modified version of that fitted to the Pulsar 200.[2] The Avenger 200 features a modified engine of Pulsar 200, delivering 0.5 bhp power and 0.4 kgf·m(4 N·m) torque less than the Pulsar. The bike has a top speed of 114 km/h(71 mph). It does 0 to 60 km/h(0 to 37 mph) in 5.18 seconds and 0 to 100 km/h(0 to 62 mph) in 20.03 seconds.
