The BMW R 1250 GS is a beautiful adventure machine that claims 136HP and 105 ft. pounds of torque in stock form. We decided to add to the excitement of the 1250 boxer engine.

Using our Works Finish R-77 profile muffler we developed a slip-on that adds 1.4 % peak HP and 1.5% peak torque. These improvements not only make this beautiful BMW more fun to ride, our R-77 makes it rumble a bit more and adds a deeper tone when on the throttle. Did we mention we lost about 5 pounds, bring on the adventure!

Proudly made in the USA!

It's here - the third generation Honda Grom. Back in 2013, we couldn't wait for the OG model to arrive on US shores and the newest version has us with equal anticipation.

With more compression, a 5 speed gearbox and new styling, the latest generation Grom promises even more fun both on the street and at the racetrack... Yoshimura is ready.

For styling, power and clearance we developed our renowned RS-9T to perform on the third gen Grom and the results are incredible as the new Grom responded like a champ. The Street Series Works Finish slip-on increases performance 11.1% max HP and 11.9% max torque! YEAH BABY!

We didn't stop there, we designed our RS-9T to offer more ground clearance and lean angle than the previous gen model. For the cherry on top we added a matte carbon fiber end cap and heat shield - Now your new Grom will love you forever!

If your serious - it's only Yoshimura. Proudly made in the USA!

The Honda CBR500R sport model and engine combo is a perfect blend of style, ridability and power. Always on the lookout to make things better, we felt that the 471cc DOHC twin cylinder engine could use a little more fun factor.

Especially on the bottom end of the power spectrum where the 471cc twin could use it most! We were even able to save over 3 pounds with our R-77, carbon fiber sleeved version. When it comes to performance Yoshimura makes it happen!

The Kawasaki Versys 1000 LT is a great platform for an ADV inspired Sport Touring Machine. With its powerful 1043cc inline 4 engine, this bike is a blast to ride.

At Yoshimura we always make it better. So we took the big Versys 1000 and went to work on creating an exhaust that can enhance all of its attributes. We developed our Alpha muffler for the job of taking on just such a task. Massive weight savings are achieved, over half the weight of the stock muffler has been shed. 9 pounds to be exact! If its power and torque you want, our Alpha answers that call too. With a consistent power and torque curve we added a strong 3% to the max. HP and a whopping 10% to the max. torque. If you own a Versys 1000 LT this is the exhaust for you!

New for 2020 is the Suzuki V-Strom 1050 XT. An adventure bike that's packed full of features with a serious powerplant.

Even though the new V-Strom's power comes from a 1039cc v-twin engine platform, we felt we could move the power in a better spot, reduce weight and make the big liter engine sound like it means business. Done!

The new Suzuki responded to every point. We chose our Street Series R-77 in beautiful and durable Works Finish with an all-new powder coated aluminum heat shield. The goal was to tune the power that comes from the v-twin engine. Bingo, our R-77 slip-on was not only 4.5 pounds lighter, it made the updated 1050 engine sound like like a real v twin.

Perfecting Suzuki's for over four decades.

The 2020 Triumph Street Triple is one of the most agile snappy middleweight naked bikes available. This machine is screaming for more so we had to oblige.

The minute our R&D team got this bike on our scanning table we knew the lines of this bike called for the new AT2 slip on system. Its raspy GP tone and its edgy lines are perfect for the UK born Street Triple. A cousin of the Alpha T muffler, our engineers threw everything out, but the kitchen sink at the new AT2 design. New styling cues include an aggressively styled matte finish carbon fiber end cap complimented by a facet-formed tip precisely trimmed using our 3-D laser cutting machine, along with a new matte finish carbon heel guard. All of these edgy high tech cues delivered in our legendary Works Finish make the Street Triple and the AT2 a match made in heaven.

The 765cc British engine, derived from power plants being used in the Moto 2 class, has one heck of a linear power delivery, but not one that we could not make better! After a few rounds on the dyno the crew in R&D were confident the AT2 featured slip-on design they came up with would deliver measurable improvements, without upsetting the Triple’s already amazing power characteristics. The sound our AT2 creates for the triple cylinder engine is nothing short of breathtaking. After considering an impressive 8.3 pound reduction in weight after installing the new AT2 slip-on, you win the Triple Crown: weight, power, and sound that will be sure to make everyone in your riding crew jealous!

The AT2 is proudly made in the U.S.A.
