Description

Following a legendary 20+ year run, the Suzuki DR-Z returns for 2025 with a fresh new design and modern updates, and Yoshimura has developed the perfect upgrade for riders who want more performance without sacrificing their ability to legally ride on public roads. If their full race system goes beyond your needs, Yoshimura's RS-12 Enduro Series Slip-On Exhaust is the ideal solution. With the included USFS-approved spark arrestor installed, this system boosts horsepower by 4.1% at 8,000 RPM and increases torque by 2% at 4,800 RPM—all while staying legal for street use. This exhaust also reduces component weight by 4.4 lbs when compared to the stock exhaust, and features Yoshimura's distinct canister design and carbon fiber exhaust cap.

Performance figures stated are reported with the USFS spark arrestor SA-21-K installed.

System Configuration Sound Level (2000 RPM) Sound Level (5000 RPM) Weight

TST Programmable And Sequential LED Integrated Tail Light For Yamaha MT-09 2021-2023
I love it. Can't stop looking at it every time I get off the bike :) Great product, feels and looks high quality. It is very bright even in bright daylight. Installation was not a problem, also there is a very comprehensive video on it by TST. Highly recommend to every owner of MT09 to buy it, it's well worth the money! Great job guys!
