Yoshimura R&D just announced the Alpha slipon exhaust for the Kawasaki H2SX. Availability is still unknown, but expect it to be widely available in the next 1-2 months as they ramp up production and fill the distribution chain.
Availability update: “Early September if you order one today.” per a Yoshimura post on Youtube. So, September at the absolute earliest. For many Northern Hemisphere riders probably not the best time for an exhaust to become available.
There will be two versions, a full carbon fiber version, and a stainless steel version with a carbon fiber end cap. The tradeoffs are a slight weight and priced difference. Otherwise they are the same slipon. You can expect to shave off about ~8 pounds (3.6 kg) by switching from the stock exhaust (13.0 lbs) to the Yoshimura Alpha.
