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. The crowning glory of this little thumper is without doubt that raw steel tank, each tank is hand painted and finished here at Mutt HQ, hand rubbed and painted to create a unique raw effect, the tank is then clear coated to protect it and the final black stripe applied with our Mutt logo. Due to the way this hand finished process is carried out each and every tank is that little bit different to it's brother, each RS-13 is a true custom, no two are identical. 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 RS-13 is no exception, our black heat treated stainless steel exhaust and silencer barks like only a Mutt can.
