FC's S4RR-Seeley type chassis is used to replace the stock Honda CB\SL frames. This frame is similar to a traditional Seeley MK2 design which has proven successful with other makes. In addition to the frame and swing-arm FC also fabricated the alloy fuel tanks, high-pipe exhaust system and rear-sets. There are two variations shown. The black one is being raced with much success in the UK. The red one, also proving very successful, is racing here in America.
