1974 B50 rear fender longer then the 1973?

Post by Jeff K » Thu Sep 26, 2019 3:16 am

I just picked up a clean and running 1974 TR5T. I also have a 1973 TR5T basket case that I am building. The 1973 parts book shows the rear fender has a "extension" that was replace by a newer 1 piece longer rear fender and that was also used on the 1974. Since the TR5T shares many of the same parts with the B50, did the B50 also use the longer rear fender?

Brand T did some strange things '73 -'74 and I have a vague recollection (and I emphasise vague) this was due to change in construction and use regulations is some countries (California?). I think on some models there were extensions to the rear light (fitted between the bracket and the lens) around this time too (but that maybe earlier), so it could be to do with position of the number plate or the like. Take this with a pinch of salt as opinions are like r-soles, everyone has them!

The B50's had different mudguards, MX had no number plate so was obviously different, and different Part numbers for the SS & T models, only having an SS type I cannot look for a difference, but I'm sure they would have been looking around to see what they had in stock and fitting whatever was available, so there is probably not a definitive answer. Is there any relevant info in Brad's books?

The difference between the oif unit singles short rear mudguard and the longer Tr5T mudguard was mainly due to the fitting of the new bigger rectangular Lucas 917 rear light assembly with the aluminium casting. The new tail light assembly was initially introduced in 1973 on the T140 and eventually became std fitment across the Triumph range, it never made it onto our BSA's as they'd ceased trading by then.

Thanks guys for the informations! Nothing beats knowledge and experience. I think that you are correct about it being due to the fitting of a larger tail light. One of my friends sold his 1974 Triumph (BSA) TR5MX to the person that I bought the TR5T from on the same day that I got the TR5T. I had bought the TR5MX 30+ years ago in great shape and sold it to him the day we picked it up for what I paid for it $50.00 LOL!. He had stored it in a heated garage and never rode it. It was the 1 gallon tanked MX and he did not have a place to ride it anymore and he did not want to turn it into a road bike. Very interesting day. I sold a 1950 Norton 500T, a 1963 B40, A 1959 TR6 and many 68-70 B25's and TR25W's plus piles of parts. I got rid of all of my pre 1971 200's and parts and kept all of the 1971 OIF models. I got the 1974 TR5T, the seller Got the 1974 TR5MX and my friend got money. At the end of the day we were all happy. I still have two 1971 Triumph T25T's and a 1971 BSA B25 , three spare frames and a pile of parts for them.
