Bonneville Streamliner Motorcycle
Few things sound more terrifying than “home-made fiberglass tube on two wheels”.
Assuming that all of the mechanicals can be restored, and that there is a stout roll cage structure, this could be fun. Beyond Bonneville, there are plenty of land-speed race locations, including in Ohio and North Carolina, so towing all the way to Utah once a year doesn’t have to be the only way to get some speed.
Just be careful.
It’s on eBay in Colorado with reserve not yet met.
