Yamaha R7 2026 + Yoshimura R77 full system exhaust in EU? Will it fit?
I’m picking up the new 2026 Yamaha R7 next month and want to pair it with a Yoshimura R77 full exhaust system. However, I’ve run into a dilemma regarding the installation of the exhaust on this bike...
Before buying the exhaust, I reached out to both the exhaust store and my local dealership. Both told me it will not fit because the 2026 EU model uses two lambda (O2) sensors to comply with the latest Euro 5+ emissions standards.
I’ve seen plenty of people online saying the R77 fits the newer models perfectly because the physical engine layout hasn't changed. But I highly suspect those riders are from the US, where emissions laws are different and they only have to deal with a single O2 sensor? (im speculating)
Since the R77 doesn't natively have ports for both of these EU sensors, I'm trying to figure out how to overcome this:
- Will the Yoshimura R77 physically bolt up to the 2026 EU header ports?
- What is everyone doing about the dual sensors? Do you weld a second bung, use an O2/lambda sensor eliminator kit/blocker, or is an ECU flash required to delete the second sensor?
I'd love to hear from anyone in the EU who has successfully installed a Yoshi or similar "US-spec" full system on a recent Euro 5+ R7. Thanks!
