Awesome, that's great! I'll do a little research as well, but I've definitely noticed the swingarms look identical!Hi pal, my rear triangle is from a mk1 heckler, I believe it's the same swingarm with the age.
It looks identical, I'll get some proper measurements tomorrow when it's lighter and less rainy!
I'm sure I've read online it's the same swinger before a certain age.
BTW my heckler frame looks extremely similar too your superlight besides a differently placed frame shock mount (someone cut and bodged it)
