Triumph Rocket 3 is available in two different variants: Rocket 3 R and Rocket 3 GT. While the Rocket 3 R is the base bike, the GT variant is essentially a touring friendly take on the regular model.

The GT variant also gets heated grips with two heating modes as standard, larger 19-litre fuel tank (the R variant gets an 18-litre unit) and forward-set footpegs for more laidback ergonomics.
The triumph 3r is a street oriented roadster while as 3gt is the cruiser variant
