I wanted the letter "A" for the highest grade. Experience the awesomeness that is Spec A!
Since its establishment in 1980, Yamamoto Racing has produced many exhaust systems and has achieved brilliant results in racing. The company's main product is an exhaust system named SPEC-A, and its lineup is overwhelmingly diverse, ranging from new models to motorcycles from the 80s and 90s.
Releasing top-of-the-line exhaust system for two models, old and new!
New products are introduced not only for the hottest models but also for the famous motorcycles of the past.
RVF400(NC30)/35) SPEC-A Full Exhaust System
The new titanium full exhaust for the RVF400 (NC30/35) was developed in response to user requests and incorporates the know-how of the company, which used to race the NC30. There are two types of silencers, single and double, and titanium silencers are available for the single only.
RVF400 NC30/35 TI 4-2-2 Kevlar
Race-specific titanium full exhaust. The silencer is carbon (Kevlar) and is designed with the mainstream design of the '90s in mind.
The assembly system is now 4-2-2, which improves exhaust efficiency.
RVF400 NC30/35 TI 4-2-1 Kevlar
This is a single silencer type. Compared to the two-piece, it looks and feels lighter.
The silencer will be available in titanium as well as the same Kevlar as the two-piece.
