Mutt Mastiff 250cc
The big dog gets a makeover.
Mutt Mastiff 250cc
DIGNIFIED BEHEMOTH
Our original Mastiff was designed to be a stand-out-from-the-crowd machine with the looks (and sound) to turn even the stiffest heads.
This year, the Mastiff is now available in a rugged Matt Green. The large capacity matt finish tank, the aged brown diamond-stitched seat, and brushed aluminium details give our original heavy-hitter an all-new modern military-styled look.
If you can’t turn some heads on this beast, then you just ain’t doing it right.
DETAILS
We’ve gone a step further with the detailing on the Mastiff.
Upfront 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 digital 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 matt green paint job and continued the theme on to the side panels. The contoured diamond stitch tan seat and grips set off the paint a treat.
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.



GETTING LOW
Get low down on the bike and you’ll see our raw satin-finished stainless steel exhaust system and as you probably already know… that’s what makes a Mutt bark like it does. We’ve also got a new heavy-duty aluminium sump guard on there, oh and you’ll also see we have some funky little CNC valve covers and oil filler cap on there too‚ details, details.
Heading to the rear we have a matching 18″ rear wheel and tyre, a shortened brushed aluminium mudguard and our tidy little Aluminium LED tail light.
ALL THE EXTRAS
We’ve been busy with some sheet metal work, the angular sump guard and matching rear master cylinder cover gives the bikes a lower-slung more aggressive look, Bruce Wayne would be proud of them.
Sat in our twin shock tube frame the bullet proof 4-stroke engine is fuel injected for extra poke and of course, this Mutt has a 5-speed box, neutral indicator, electric start and everything else you would expect to find on the controls of a modern bike.
The Mastiff is the big dog of small cc machines, perfect for city carving or bending around country lanes alike. So, if you want to be king then get yourself to your local Mutt dealer and check out the Mastiff in person.
