Mutt Mastiff


Mutt motorcycles, produce a range of small capacity, factory custom bikes that look as cool down the bike meet as they will outside the Bike Shed. Powered by a reproduced Suzuki 125 engine and with 11.8bhp. They say;

We’ve been building serious custom bikes for a very long time. But due to the size, and expense of high end, vintage motorcycles, the custom bike scene can seem quite inaccessible. We wanted to change that…

So, we started applying that same build quality and style to small cc bikes that are easy to sling round busy city streets, bend round country lanes, and charge on the open road. This would take small cc motorcycles to the next level, and our approach meant building them a little differently.

This is the Mutt Mastiff – a beefed up version of their super popular custom 125s. Mutt say that the new Mastiff is the ‘King of the Mutts’, so they’ve gone to town on the standard bike starting with the tank. The Mastiff has a larger 17 litre tank, which is 5l bigger than the standard Mongrel The tank is finished off with a Monza-style fuel cap and too-cool-for-school flat black and silver paintjob.

The Mastiff has black 18” spoked wheels, wrapped with a deep tread set of knobblies, It has a CNC machined LED indicators, headlight brackets, fork caps and head stem nut plus the brushed alloy mudguards, proper headlight grill and the stainless mini-speedometer. It includs a stainless-steel pipe and a heavy duty aluminium sump guard plus some more dainty details like the machined oil-filler cap.
