Mastiff 125

Brutal yet refined, the Mastiff 125 is the king of the Mutts.

The Mastiff’s pedigree stands out with that monster tank topped off with a Monza style cap, a custom flat black and silver paint job, and super-wide deep tread tyres on 18” black rims with stainless spokes.

The contoured diamond stitched tan seat just begs you to stroke it and take this hound out for a run.
