The 2006 Avenger came with a 180 cc engine, producing 16.3 BHP and 15.3 NM of torque. The motorcycle should not be bought for INR 30,000 as its market value comes out to be INR 18,000-20,000 only. You should buy it by checking all the essentials like engine, gearbox and suspension thoroughly as it has been driven for 9 years and would have covered more than 50,000 km. Tyres and brakes can be easily replaced as they does not cost much and require regular changing and checkup whereas the engine and gearbox problem can ruin the bike’s life. You can get it checked from the Bajaj authorized service center before buying.
