•1dI am planning to buy the Harley Davidson X-440T, but some friends are suggesting choosing between the Guerrilla 450 and the Triumph 400. My usage will be limited to city riding. Please suggest which bike would be better, considering price, mileage and service cost.

Purely from a price and fuel economy standpoint, its the 350cc Triumph Speed 400 that has the advantage over the other 400-odd cc machines you've shortlisted but there's more to choosing between bikes than just these two factors.
The Harley-Davidson X440T is one of very few long-stroke, air-cooled, large-capacity engines available today and it is a genuinely likable machine to ride. It may not be as quick in outright terms as the Guerrilla and Speed but even so, it makes for a lovely city bike owing to its characterful engine paired with plush suspension and neutral ergonomics.
If you want maximum thrills and don't mind lower fuel economy, the Royal Enfield Guerrilla 450 is the one to go for. Its punchy engine and sporty chassis work wonderfully well together, although of the three it is the least comfortable machine. This is not to say the Guerrilla is an uncomfortable bike, its a taut and sporty machine and you should be prepared for that going into your purchase.
The 350cc Triumph Speed 400 is a bike that's in between the two, amalgamating a quick engine and good handling, although its neither as characterful as the Harley bike nor as fun as the Royal Enfield bike.
Service cost should largely be on par for all three and we'd advise you to speak to your nearest authorised dealer for each as well as take a test ride of all three so that you make an informed decision.
