At Malossi, we want to hear engines sing. The solo voice? The Racing Exhaust MHR 100 for scooters and motards.
When the engine sings, every component is in perfect harmony, tuned to deliver peak performance. It means your time on the track will be insane, and your dedication as a rider might just be rewarded with victory. But that’s not all—this music guarantees an electrifying riding experience, while you dart fast as a bullet.
The Malossi Racing Exhaust MHR 100 was designed and built to sing, but with one ultimate goal: to achieve maximum performance when paired with the 100cc cylinder for which it is designed.

Malossi, “the exhaust guy”
If Malossi is known as “the exhaust guy,” there must be a reason. Our advancements in exhaust systems have never been random improvisations, they are the result of advanced fluid dynamics studies capable of determining the ideal shape and size of racing scooter exhausts. This isn’t child’s play, you know.
Every MHR 100 racing exhaust is crafted from metal sheets with an exact and constant thickness of 0.8mm, laser-cut, meticulously assembled using TIG and MIG robotic welding as well as manual oxyacetylene welding, and finally hand-hammered by skilled artisans. Each one features a calibrated nozzle, whose dimensions meet the strict tolerances required to maintain optimal internal pressure. Every unit is coated with a clear finish and comes with a black anodized Nitro aluminum silencer, proudly displaying the Malossi logo.
Racing exhaust MHR 100: born to win
The development of racing scooter exhausts – designed for Malossi Trophies – proceeds hand in hand with that of Malossi cylinders, and to achieve maximum performance, it’s essential to always match the exhaust with the cylinder for which it was designed; specifically, we’re talking about high-performance engines, therefore the 100cc cylinder. The combination works even better with the crankshaft for the 100cc cylinder.

The cylinder mounting system features a three-hole light alloy connector, engineered to ensure optimal flow of exhaust gases, enhancing their dynamics. We’ve also simplified the connection system for the black anodized Nitro aluminum silencer, now seamlessly attached to the exhaust expansion chamber with an elegant, lightweight single-bolt fastening system.
The MHR 100 Racing exhaust for scooters and motards is designed to deliver exceptional power gains at mid and high RPMs. With this new product, Malossi expands the Trophy exhausts range, which unleashes their full potential and maximize performance during competitions.
We are deeply committed to the Malossi Trophies: we strongly wanted them, to give all young people who want to pursue sporting activities in the two-wheel world the opportunity to become the riders of the future and make their dreams come true.
