Hi.
I have one of these lovely little trials bikes. I use mine here on the Isle Of Man in our very active trials centre. From what I can gather Colin Seeley built the frames, as the sticker on my tank states "for Honda UK" and his brother Richard Seeley built the engines and gave them his own engine numbers. Mine has Marzocchi forks. The fork clamps. I can't decide if these were made by Seeley or are Marzocchi too. The rest of the bike appears to be Honda TL. Ie the hubs and brake shoes. I love the hand made appearance of the air box and beautiful ally tank under the fibreglass seat / tank unit. (although the work is excellent) It is so typically british and each bike must have taken forever to manufacture, and must have cost a fortune when new!
