Does Bajaj Avenger Cruise 220 have ABS or not?

No, but you can easily replace them after market.... But for the better performance and better shock absorbing dot replace... My friend Bajaj Avenger 160 streets front alloy were damaged when it hit a path hole when we were going to rajasthan mine 220 cruise also hit ... But 160 alloy got damaged and 220 cruise got just a little bend

Hell yeah! I just completed my 3000 km journey to Ladakh and back, and boy, the bike was almost perfect (as opposed to a few minor issues). Now by mountain trips, do you mean a weekend ride to your nearby mountain range or to the highest motorable road in the world at 18380 ft? If you said either to the former or the latter, then the bike performs great in any terrain - be it straights, off-road or ghats. The only issue I faced with on the Ladakh ride is the drop in power (the engine couldn't get the oxygen it required for optimum combustion since the air is thin up there, hence I could only manage 60kmph in the toughest terrain). In the luggage department, you could install side boxes (The studds cruiser one is the best) or tie a backpack with a bunjee cord to the back pillion rest (available only in the cruise 220), which makes for a great makeshift support. Cheers!

Yes you can. Both Rims and Tyres (Front and Rear) will change. Ask the Bajaj showroom workshop manager/Service engineer to replace your existing rims and tyres with the Avenger Street 220 tyres. Avenger Street has Tubeless tyres and Alloy rims. This will cost you in the range of 8,000/- to 10,000/- (all inclusive). Don't buy alloy rims from market as you will get only 1/2 designs hardly available due to no demand and that too from a not so reliable manufacturer with no warranty.
