Yamamoto Racing’s “Spec A Premium Edition” undertail full exhaust for the CB400SF/SB is back as a Webike limited edition reproduction!

When we introduced the Undertail Full Exhaust for the CB400SF/SB on our Japanese site it received a huge response. As a result, Yamamoto Racing has decided to re-release it as the "Spec A Premium Edition"! Reservations are now being accepted and quantities will be limited.

The most challenging exhaust for the CB400SF/SB is back!

The Undertail Exhaust for CB400SF/SB, which had rumors of a re-release, is making its comeback as a Webike limited edition reproduction model. Although Yamamoto Racing had previously stated on their official social media platform that the exhaust would not be coming back, this decision was made due to a greater-than-expected response.

This release is a Webike limited edition model, and because it is a limited edition, it has special specifications. First of all, the original stainless steel exhaust pipe has been kept, but the silencer cover material has been changed from carbon to titanium. The result is a finish that combines ruggedness and beauty. In addition, a laser printed logo has been added to the silencers to match the change to titanium. The left and right silencers feature special logo designs, "SPEC-A -limited edition-" and "YAMAMOTO RACING -limited edition-", respectively.

The "High Mount Kit" for ride height adjustment has been changed to a black coloring to better match the bike design, and sure to delight Yamamoto Racing fans, a special SPEC-A Titanium Keychain will also be included. These original titanium plate keychains are surprisingly handmade one by one, and of course, since they will not be fore sale otherwise, it makes for a great collector's item.

Orders will be stopped when the planned production quantity is reached, so riders who are interested are encouraged to check it out right away.
