1959 Triumph Speedtwin
This bike is a Triumph C range 500cc Speedtwin 5TA, it is not in original factory trim.

It was supplied by the Triumph factory to Pikes Garage in Alphington Street Exeter, on the 26th Aug 1959. I've owned it for 27 years. It's a lightweight and easy bike to handle, the engine is a typical twin cam Triumph and needs revs to perform. It will cruise nicely at 60 mph and you can keep up fairly good averages on a run. Handling and braking is good for a late fifties twin.

Over the years I have made a few mods to keep it on the road. It runs a Kirby Rowbotham / Boyer elec ign conversion in place of the 18D2 distributor with a twin fire coil. Len Patterson converted the head for unleaded fuel, I had no choice really , the valve seats had worn so badly that the valves were hitting the rocker spindles. It has a concentric carb and sixties air filter assy. The engine has low comp standard 7. 1 pistons. I use a Commando spin type filter assy, mounted underneath the gearbox, and magnetic sump plug. The gearbox has the later stiffened cam plate, and needle roller layshaft bearings.

The fasteners are mostly stainless as are the wheel rims and spokes. I use Thunderbird fork springs and Tiger 100 spec rear shocks. The electics are 12 v and I use the later sixties zener diode system.

The bike gets used for general running around and Club runs. I've thrown it up the road once about twenty years ago and it has only broke down once but still got me home stuck in second gear.

It's a great fun , good looking bike to own and I really enjoy riding it.
