Colin Seeley is one of the racing world's great chassis designer/producers. He went on to construct a prolific number of fine handling frames for street and trail, and was unfazed whether engines were 2-stroke or four, or if sourced from England, Japan, or Germany. Having cut-his-teeth on successful frames for AJS/Matchless 'singles' he was perfectly placed for the new breed of speedy, poor handling Japanese 'strokers', which by the late 1960s, were out-running all the British 'cammy' 4-strokes. Barry Sheene famously turned to Seeley in 1971 when he was seeking the best chassis in which to house his recently acquired TR500 Suzuki engine. Thus mounted, Barry secured his first British Championship. He later claimed "...it was the best handling bike I ever rode!"

Constructed of Reynolds 531 tubing the machine's functional frame has the plus point of an authentic paint finish. Supplied in April 1972 to New Hampshire's Ross Seeley Racing Co, the iconic racer is still owned by the original first customer! Un-raced, and with barely 100 highway miles under its wheels, this wholly original machine was dry-stored from 1975 (at which point all fluids were drained) until 2011. Referring now to those all too few exciting miles in the saddle the vendor recalls "...it was a rocket-ship; unbelievable!" He also confirms the stock 'triangular' Dunlops were changed at the time of purchase, since when a rotted front tire has been replaced. Offered with some original technical literature this pedigree racer demands a close inspection.
