1957 Triumph T100RS

Road racing in America has never been a priority. From the beginning it has always been one straight, long or short, followed by a left turn. So when I see a ROAD RACER offered on eBay, I always stop and look. This Triumph T100RS stopped me this morning and will keep me busy for some time.

By 1950 Triumph had stopped delivering Works prepared Grand Prix level bikes to customers. Instead they offered a race kit, which came in a box that was full of all the goodies to turn you T100 into a GP bike. This moratorium on  offering race bikes direct from the factory was short lived because of the demands of US dealers like Johnson Motors (before they sold T-Shirts they were a force in racing in California and the rest of the South West.)

Clipping from Show & Go Cycle Shop

Based on the Triumph Tiger T100 which was first offered before the war in1939 and then after the war from 1946-1973, the 500cc Triumph’s were popular because of the AMA class C racing rules. Because of the influence of Harley-Davidson, the maximum displacement for OHV engines was 500cc until 1969. So if you wanted be competitive against the 750cc flat heads, Triumph was your best option.

Found scanned to a Motorcycle forum while researching T100RS

For such a rare bike you would expect the seller to tell us why we will never see one come up for sale. I found that the racing Tiger 100 first came out in 1953 as a T100C, the C standing for Competition. In 1957 they changed it to a T100R for Race. What you would get was an Alloy cylinder compared to the standard iron lump. The twin spigot cylinder head was also aluminum and offered twin Amal G.P. TT carb’s with remote float. The internals were build with a larger intake valve to match the larger carbs. A race specific cam, with race ready tappets and valve springs kept the valves moving. Spark was delivered by a racing Lucas Magneto because you don’t need lights on a race bike.

It appears that the new competition bike was offered in both T100RR and T100RS forms. The second R was for rigid, and not having rear suspension was a benefit on the dirt tracts of America.  The RR would get reverse cone mufflers on the right side of the bike, a smaller gas tank and no front brakes, because you don’t really slow down when making left turns only.

This T100RS has a Sprung frame, good for turning left and right. A front brake was needed and a larger gas tank was added. It would also come with a rubber mounted tachometer, rear sets, racing seat and open megaphone. Walking into the showroom with $947 would have bought this bike in 1957. Wonder what it will take to win this auctionin 2011?BB
