Early rigid rear end or sprung hub models had some strong suicidal tendencies. Even the post ’54 swinging arm models liked to waggle their back end and run off the road in corners. With a decent rebuild the pre-unit motor’s relatively smooth and reliable, especially when constrained by the handling. Also TR5 version which went from early 25hp to late 33hp motor but lacks the Tiger’s panache.
