Like it’s RS-13 bro this little ripper shouts home brew custom bike. With all the hallmarks of a true custom Mauler is the blacked out version of sought after RS-13, narrow street tracker bars to the fat knobbly tyres. The beauty of this bike is we build it for you, no need to spend months in the garage, all you gotta do is ride. As with The RS-13 the Mauler is true to form, lightweight, stripped down and cooler than a polar bear’s PJs.


Following the classic Mutt stylistic approach - retro styling and riding experience with modern reliability and ease of operation. The 125cc air cooled single cylinder engine is housed in our tubular twin shock frame and feels like a much bigger bike, a perfect machine for carving up inner city traffic or just as at home slamming through the twists and turns of the countryside. Running narrower handlebars for an upright aggressive riding position, it’s perfect for hacking through the city traffic and that super bright halogen headlight lights up the road ahead with ease from behind the matt black grill. Keeping to a retro classic roots it runs 18” wheels front and rear shod with super fat, deep tread fat knobbly tyres.


Short black rear shocks and wide yokes with telescopic forks keep the bike firmly planted on the tarmac. For rider comfort and retro vibe, it has diamond pattern black grips and a choice of black diamond pattern black seat or a distressed tan tuck n roll seat. In true Mutt style we’ve fitted all black wheels with black spokes, flat black aluminium mudguards and of course our neat little black LED aluminium tail light and LED indicators.

We kept being asked to make the RS-13 ‘more black’ so here it is, just as you asked for. But how does it sound? Well, if you are a Mutt fan you will know that all our bikes have a healthy low down rumble and the Mauler is no exception, our black heat treated stainless steel exhaust and silencer barks like only a Mutt can.
