BSA
C15 Gallery
BSA had acquired
the Triumph marque at the start of the 1950s
and the lightweights towards the end of the
decade owed far more to Triumph than to BSA.
Chief among them was the 1952 C15 Star. A 250cc
fourstroke almost totally derived from the 200cc
Triumph Tiger Cub. Even so the new model seemed
both up-to-date and sophisticated electrics.
As with its Triumph predecessors, the C15 and
its derivatives suffered from minor electrical
problems, oil leaks and somewhat complicated
maintenance routines. More BSA

1958 saw the beginning of a completely
new departure from the usual engine/transmission
design with the introduction of unit construction
machine in place of the 250cc C12. The first
of this new breed of motorcycle, the 250cc
C15 Star, was an instant success. It had
a clean, uncluttered appearance and provided
reliable and economical transport. |

| BSA C15S Elstar Grasstrack Bike |
 |
This bike was ridden by Tom Swallow,
he ran a BSA Dealership and produced a
magazine called Flywheel whilst he was
held in Stalag IVB. This was one of his
bikes he raced in grasstrack. Based around
a BSA C15 scambler.
The engine is a c15s and runs on methanol
and castrol R, it has a high compression
piston and close ratio gearbox, racing
cam, it runs a total loss ignition setup.
The barrel has been turned down to save
weight. It has a large size Amal gp carb.
The frame I believe is Elstar and uses
a bsa s-arm and highly modified sub-frame.
It has r-shock which are extremely stiff
and upside down small front forks. It
has cub/bantam bubs which have all been
drilled and sculpted out. The oil tank
has been reduced in size and petrol tank
is nice and chrome. The bike does run,
and was used several years ago at Red
Marley Hill Climb by Tom Swallows son.
