To cook this one up, we took all the pretty candy from our other Mutts, added some technical upgrades, and applied a dash of new styling. This all comes together to make the GT-SR one of the highest spec bikes in our range. The latest street bike addition; it's the perfect all- rounder with a low centre of gravity, a big capacity tank, and wide road tyres. All with that down-and-dirty Mutt DNA running right through its veins.
