Meanest Monoshock on the Market

Mutt Motorcycles has delivered another thump on the nose to the Motorcycle industry by releasing our snarling Razorback onto the city streets.

Another new addition to the Mutt pack, undeniable Mutt DNA runs through the Akita front to back. But we’ve added a few twists to turn it into the ultimate pavement-poundFeaturing a brand new monoshock frame designed in-house at Mutt, the Razorback casts a different shadow to our fat bikes. Like all our bikes, this new frame has custom and classic roots. No ugly pressed aluminium – just a good solid tubular frame with a beautifully simple rear loop.

Get The Skinny

Look in more detail around the bike you will see some other neat touches you won’t have seen before. Starting at the As with all our 125’s the Razorback is powered by our super-solid four-stroke black number and a Delphi fuel injection system, fed by our custom skinny tank. Oh, the tank? Yep, that’s another new item specific to the Razorback. Have you ever tried to mount an old 70’s tank to your one-off custom build? You have? Then you’ll be familiar with welding on new tabs, removing dents, blowing holes through the tank with your trusty TIG welder and all the other aggro that comes with fitting vintage parts to bikes. Trust us – we’ve done a bunch of them.

Follow the forks upwards, and you get to the bars. These are our aluminium low-rise bars as seen on many of our bikes – but check out those lightweight aluminium and rubber grips, and branded bar ends. These are complemented by our Mutt CNC fork caps and head stem nut. The devil definitely is in the dWith that in mind for a production bike, for the Razorback we designed our own tank, taking influences from the many vintage tanks we have fitted to over the last 20 years. We took styling cues from several vintage bikes, but it is all Mutt, and has that one-off custom vibe you’ll never get from any other production bikes.

I Can See For Miles

Moving upfront, we have our low-rise Mutt Handlebars and a black contoured slimline seat. The Razorback is a tall bike, and with a seat height of 88cm, it gives the rider a great upright riding position and the ability to have a clear view above traffic. It’s an absolute blast to ride – chucking this little fella into corners will bring induce a bug faced grin to any fizzog.

Inverted forks held by wide yokes help soak up the bumps on the potholed city streets and country tracks, and another 18” aluminium rim with stainless spokes sits up front shod with fat rubber in the Mutt way. The Razorback is finished off with a full stainless steel exhaust system with a fat stubby silencer, and an aluminium bash plate.
