1950 Triumph Thunderbird

What can I say, but a 1950 Triumph Thunderbird will always get my attention. And this one offered up for sale appears to have been owner for 90% of its life (or more?) by the same owner. That fact will  get more attention then most.

From the seller

1950 6T 650cc TRIUMPH THUNDERBIRD. I restored this motor in 1957, adding 8.5 piston, alloy rims, chrome spokes, with chrome nuts and bolts throughout assembly. Painted it in Tiger 100 colors and added the improved 7″ Nacell to use sealed beam. I’ve ridden it since then, adding 17,500 miles. Picked up a 1974 Triumph Trident in 1978 and have put fewer miles on the 6T. In 2010, I affected some updates; New seat Refreshed worn leather on the saddle bags New Avon tires and tubes. Greased wheel bearings and spring hub. This is a MK II spring hub NOS from dealership days New AMAL concentric carb New petrol tabs (pet cocks)New fuel lines New gel cell battery, now no maintenance with stainless steel battery cover March 2011 I trailered it to Daytona and rode about 400 miles with no issues March 2012 I trailered it to Daytona and rode about 300 miles with no issues Additional items include; Original tool bag with most of the original tools and some extras

During the post war years the British Motorcycle Industry listened to the US market, and when they said bigger is better, Triumph gave them what they wanted. The Thunderbird was based on the Pre-War Speed Twin, and Triumph Tiger T100, but gained 250cc worth of displacement. The fact that Marlon Brando also made it famous in the Wild Ones didn’t hurt sales.

Like all the Triumphs of the time, the 6T Thunderbird was first offered in a rigid frame, with a Pre-Unit engine and transmission. The engine, with its single carburetor, produced 34bhp at 6300rpm which enable the, fresh off the factory floor, bikes to average 92mph for 500 miles in a publicity stunt on the famous Montlhéry track outside Paris.

Designer Edward Turner addressed the rough ride of the rigid frame by developing a Sprung hub, which put the suspension inside the rear hub. A unique answer to the question, this only lasted until 1954 when all Triumphs received there own suspended frame. If you do buy this 1950 Triumph Thunderbird, you will get to experience the sometimes frightening ride of one such sprung hub. BB
