Introducing Yamaha YZF-R7 kit parts from Yoshimura R&D of America. Yoshimura's latest line of kit parts for Yamaha YZF-R7 models include key components that not only give the R7 more horsepower, but also provide it with the competitive edge it needs when lining up on the grid.

These products, designed for closed-course competition use only, were developed by Yoshimura R&D while building #ProjectR7 piloted by Ari Henning and tested by 2022 MotoAmerica Twins Cup Champion Blake Davis, and each of the kits listed below are legal for use in MotoAmerica Twins Cup class.

July 13, 2022: It's been about 9 months in the making and it was time for #projectr7 to take to the race grid in full dress.

Here are a few of the kits now available, with descriptions and photos provided by Yoshimura:

(2022-23 Yamaha R7, 2017-22 MT-07 AT2 Race Series Exhaust FS TI/TI/CF)MSRP: $1399P/N 13720PP720

When it came to crafting a special race exhaust for the Yamaha R7, we pulled out all the stops. Created with premium alloy material, then prototype after prototype, until we reached the final test system. On a stock engine with no mods and 91-octane pump fuel, this new system creates +6.2% max HP and +2.7% max torque. This system is designed to create even more performance with motor work and our airbox so the gains we publish are just the start of a powerful package.

Losing over 11 pounds from the stock system, our AT2 is ready to make your R7 move! The design of the AT2 tucks nicely under the lower cowling to keep it away from harms way as much as possible.

(2022-23 Yamaha R7, 2018-20 MT-07 Airbox Kit)MSRP: $499P/N 750BG137200

While testing and developing the Yamaha R7 airbox, we found that the stock configuration doesn't allow near enough near enough air to feed even the stock configuration for racing. Enter the new Yoshimura Airbox Kit.

This kit single-handedly increases performance on a stock engine giving it huge gains! In fact by just adding our airbox, you can expect 8.5% increase in max HP and 4.8% increase in max torque! Add our AT2 Race Series system and the performance really starts to climb.

(2022-23 Yamaha R7 Swingarm Pivot Kit)MSRP: $649P/N 450BG137200

Optimizing the Yamaha R7's chassis for the increased speeds and lean angles of racing is extremely important: millimeters count. Our Swingarm Pivot Kit gets the Yamaha R7 pointed in the right direction and helps keep it there giving the rider confidence even in turns where the grip is marginal.

By flipping the two pivot inserts, the racers can increase or decrease by 1.5mm. That may not seem like a lot, but the changes are dramatic, enough to make the R7 feel like the podium contender it is! When combined with our Suspension Link part #400BG137200 the two components enhance the handling of the R7 perfectly!

(2022-23 Yamaha R7 Aluminum Subframe Kit)MSRP: $699P/N 900BG137200

If you’re serious about racing the Yamaha R7, Yoshimura's new aluminum subframe is a must-have. First, it carries a weight savings of over 4 pounds over the stock configuration. Next, this subframe includes and aluminum battery and wiring tray to mount your battery and protect your wiring harness from tire debris.

In the event of a crash or components get damaged, we carry all of the items you would need so you can repair your machine and get back out onto the grid for your next race. This unit requires a skilled installer!

(2022-23 Yamaha R7 Suspension Linkage Kit)MSRP: $549P/N 400BG137200

OEM linkage is designed for street and two-up riding, low ratio, high progression. Engineering the Yamaha R7 to be more stable at the higher speeds for racing is crucial. So we enlisted a world-renowned suspension/chassis engineer to get the R7 right for racing. Our suspension link system works by modifying the linkage ratio and progression with a higher ratio and adds more linear progression. This set up is designed to work well with the stock OEM R7 front end. This link is designed for enthusiast track days and professional racing. When combined with Yoshimura Swingarm Pivot Kit part #400BG137200, above benefits can be maximized even further.

(2022-23 Yamaha R7 Camshaft Kit ST-2M)MSRP: $1459P/N 700XX137200

Camshafts are the heart of any engine and is where tuning started for us. In 1954, Hideo "Pops" Yoshimura was grinding cams by hand. A lot of time has passed since then, one thing has not… passion. Today, Yoshimura cams are created in Japan from a special steel alloy billet and is just what the CP2 engine needs to make more grunt.

Installer should be familiar with engine building, these are not drop-in replacement! Cams must be degreed during installation. Yoshimura will offer complete engine build services for the Yamaha R7.
