May 17, 201412 yr Hi Spent the day with my dad today at midvaal raceway racing classic gp bikes. This bike belongs to a club member named Terry. 250cc single.
May 18, 201412 yr It's a Bultaco Tss racer. Beautiful bikes, Berry Sheene rode them in his early career.
May 19, 201412 yr Author Is it watercooled? Looks like a rad up front! It is with assisted cooling of fins on the cylinder. My dad says they are a pain to run because they need to be moving to stay cool. Any delay in the start of a race, they have issues.

May 19, 201412 yr They aren't realy a problem , but they have to be up to working temp before riding hard as they are prone to cold seizures ,in cold weather the rad has to be partially blanked off to keep the temp up . Water cooled TSS bultacos work on the thermo syphon principle , they have no water pump . The frames are made from the same stuff as the early pre chrome moly stuff and handle realy well , in fact when the 350 AJR replica was made in the late 90s some people said it didn't handle as nicely as an original as it was too stiff .
