1963 BSA C15 SS80 Sports Star, 250cc. Registration number CME 107A (non transferrable). Frame number C15 38709. Engine number C SS 2968.( please note the V5C says C552968) In September 1958 BSA introduced a new ‘250’ that would provide the basis for an entire range of singles in capacities up to 500cc. This newcomer, the C15, featured a compact overhead-valve engine and unitary four-speed gearbox. Alternator electrics and coil ignition were features, early models being distinguished by a distributor-type points housing. The engine/gearbox unit was housed in a conventional cradle frame with bolt-on rear subframe. Trials and scrambles versions were offered as the range expanded during the 1960s. A sportier version of the C15 was introduced in 1961 called the C15 Sports Star or SS80 with the 80 representing the maximum speed of the bike in a similar way to Triumph’s normal naming convention. The SS80 used a roller big-end instead of the plain bearing on the C15 Star, a sportier camshaft, a higher compression piston, a larger inlet valve and a larger bore AMAL 376 carburettor to give more output power. It was similar looking to the C15 Star except for the use of chrome plated mudguards. It continued in this form until the 1967 season although it was renamed the C15 Sportsman in 1965. This example is quite rare amongst C15's and should make a worthy recommissioning project, it appears relatively complete but prospective purchasers should satisfy themselves. Sold with the V5C and SORN certificate.
