    Product description

    - Bonneville T100 all versions 2017+
    - Bonneville T120 all versions 2016+
    - Street Twin 2016-2022
    - Street Cup 2017-2019

    Note: Not compatible with a center stand (if your bike has one, get rid of it and use our workshop stand, much smarter solution !).

    Stainless steel exhaust line with two silencers situated under the engine for a retro/sporty look, a better sound, lower weight and a noticeable performance gain.

    Weighs only 6kgs, 4kgs less than the original exhausts on a Bonneville.

    The downpipes include placements for the O2 sensors (which you can also easily remove).

    Noise level intermediate (one step louder than standard, but nothing to get you in trouble). Listen to them here (video).

    Available as an option with integrated (invisible) catalysts, in this case the system is supplied with Euro4 certificate.

    Does not exist with Euro5 certification.

    Designed and crafted by MASS Moto in Italy. MASS is a small company that combines passion and high technology to produce products of very high quality and perfect finish. All MASS products are made of aviation-quality stainless steel and are type-approved for Europe.

    Medium difficulty installation with some mechanical knowledge.
    Requires no modification of the bike, totally reversible assembly.

    No need to reprogramme the ECU, which is self-adaptive on the 900/1200cc Twins.

    24-months warranty.
