Yoshimura - 'Going Big' on the R7
When Yoshimura gets a bike in its crosshairs, it has the habit of really 'going to town' on its possibilities - really wanting to 'own it'.
Late last year, Yoshimura R&D America confessed to its latest addiction with a slew of parts for the Yamaha R7. From suspension linkage and swingarm pivot kits to a 4 lbs lighter-than-stock aluminium sub-frame kit, airbox kit and R7 camshafts, 'Yoshi' decided to 'go big'.
Earlier this year it released details of an AT2 titanium race series exhaust, and this summer it followed that up with an AT2 stainless race series system.
"When it came to crafting a special race exhaust for the Yamaha R7, we pulled out all the stops. Modelled after the titanium version, this Works Finish stainless system is the perfect balance between performance and value.
"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 +5.7% 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 9.6 lbs from the stock system, our AT2 is ready to make any R7 'really move'. The design of the AT2 tucks nicely under the lower cowling to keep it away from harm as much as possible".

Obviously for "closed course competition use only", it features a full stainless steel construction and includes an M18 lambda sensor bung at the tailpipe. This system works with a stock bike, but is designed for highly modified race-tuned engines and was developed by Yoshimura while building #ProjectR7 piloted by Ari Henning and tested by 2022 MotoAmerica Twins Cup Champion Blake Davis. An optional sound insert kit is available for -4 dB if required.
Additional new exhausts from Yoshimura R&D so far this year include slip-ons for the Kawasaki ZX-4RR (+3.0% hp, +4.3% torque) and for the Suzuki V-Strom 800 DE (+1.7 hp and +1.6% torque).
