The all-new 2025 CFMOTO Ibex 450 adventure bike is here and Yoshimura's offering a RS-12 ADV Street Series slip-on coming soon for your new adventure machine.

When we first heard that CFMOTO was going to utilize their 450 twin engine platform on a new adventure chassis from the already popular SS and NK models, we got excited. Once the Ibex 450 showed up in our shop we got right to work. After a ton of design and testing we are pumped to share what we came up with.

RS-12 ADV features:

• Engineered for the demands of the off-road world.
• Aggressive, intelligently designed, asymmetrical shaped RS-12 profile allows maximized muffler volume to help manage sound, add performance, weight reduction and provides more clearance for tire and brake caliper.
• Works-look matte carbon fiber end cap and custom carbon fiber heal guard with industry leading design, innovation and detailing as expected from Yoshimura.
• New RS-12 end cap design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry.
• New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters.
  
• Proudly designed, developed and made in the USA!
