We wanted to make the Mastiff the king of the Mutts, so with that in mind we decided to add a little love here and there to make him a little different yet still retain that unmistakable outline of a Mutt Motorcycle.

First up is that monster tank. We designed this tank specifically for our two newest models the Mastiff and the GT-SS. We wanted to keep the classic tank shape but add a helping of steroids, so we boosted the size to 15 litres. Sitting on the Mastiff and looking down at the huge tank is a beautiful sight. We topped the tank off with a neat Monza style chrome cap for that classic British vibe.
We’ve gone a step further with the detailing on the Mastiff.
Up front we have a super wide deep tread tyre wrapped around a black rim 18″ with stainless spokes, cropped brushed aluminium mudguard, headlight grill and our beautiful stainless steel mini speedometer topped off with a set of anodised black Mutt bars.
Look closer and you’ll see some super neat little details. We’ve got those super cool machined LED indicators, CNC machined headlight brackets, fork caps and head stem nut and those oh so pretty black anodised handlebar clamps. Looks pretty neat eh?
Moving along the bike we’ve gone for a custom flat black and flat silver paint job accentuating the shape of that hefty tank, we’ve continued the paint theme on to the side panels. The contoured diamond stitch tan seat and grips set off the the paint a treat.
