My dad and I have started a Rupp mini bike restoration on what we think is a 1971 Rupp Enduro. We think that’s what it is but it’s been modified so much that we can’t identify it, a Rupp parts salesperson said that it is likely to be that year/model. We know it’s a 1971+ but model could be many including a rare and sought-after Black widow!

Like I said the bike is heavily modified, the frame was reconfigured to eliminate the trademark Rupp engine slant, the engine has been replaced, a headlight support was added, and many more mods that’ll going to make this resto a little more expensive than it should be.

After:

Anyways, our plans are to restore it to factory spec (my dad’s plans, I want to hot rod it!). We’ve already began by tearing the thing part and cutting welding the frame back to factory spec (whole weekend project). Next up; stripping the paint!
I’ll post status of the bike during the resto.
There are few Rupp sites, this one is helpful.
