There’s a new dog in town... and it’s a vicious bugger.
Say hello (but don’t get too close) to the Razorback - the latest offering from the crazed minds of the guys in the Mutt Lab.
Mutt Motorcycles has delivered another thump on the nose to the Motorcycle industry by releasing our snarling Razorback onto the city streets.
Featuring 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.
Wide Open Space
Look directly underneath that rear loop, and you will see a whole lot of… nothing - diddly squat. We wanted to keep the area underneath the seat as clean and open as possible, and we’ve achieved it by locating all the electrics and battery in a neat little package below the seat and adding a narrow aluminium swingarm, which leaves that beautiful wide open space above the back wheel. Oh, and the wheels are of course aluminium rims with stainless spoke. Another nod to our custom bike building history.
Get The Skinny
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.
With 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 of 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.
Everything else is what you would expect on a Mutt Motorcycle; a smooth 5-speed transmission; rider- friendly controls; mini custom speedometer; stainless steel fasteners throughout; combined braking with braided hoses. It also comes with bags of attitude as standard.
