I lovingly restored 2 Bultaco's and actually have them in the book "The History of Bultaco" by Jeff Conboy. One pic is with me riding and the other is with Gary Jones on one at Southwick in the ACR "Running of the Buls" race. And although they are beutiful bikes I had the same problems in the 2000's with them that I did in the 70's....But I did love them just wanted something with a bit less hassle.
I did have RM 125's as well as a kid so I started looking for one of those and whats nore fun than a 125...NOTHING!
Here's the last race of last year, 125 FUN
