To a certain extent there are. There was a guy on Ebay selling semi rolling chassis on a hardtail frame. Included the rear wheel and sprotor with caliper and rear break res. Price was right too. It was a business with a website other than the Ebay listing but I haven't been able to find it again. There are other people making hardtail frames for our engines though but it's up to you to collect the rest of the parts.

I learned all I need to know about life by killing smart people and eating their brains.
