Featured Listing: 1974 Bimota HB1 Clone for Sale

Today’s Featured Listing Bimota HB1 is a bit older than we generally list on this site and isn’t technically the real thing: it’s a lovingly-crafted replica. Considering Bimota only made a handful of the original HB1s, that’s pretty much the best way to get your hands on one anyway… And while Bimota has been has struggled to find financial success and has been in-and-out of bankruptcy, there’s no questioning their racing pedigree and commitment to the sportbike art, so it seems fitting to showcase this machine here on our site.

Fans of RSBFS might be most familiar with their recent offerings that seem to offer up more bling and exclusivity than outright performance, but the decline of Bimota is more about the major manufacturers catching up to Bimota than any real failure in terms of concept or design. Bimota’s beginning was pretty unlikely, since the company was originally founded to manufacture heating and air-conditioning systems, But it’s hard to imagine that founders Valerio BIanchi, Giuseppe MOrri, and Massimo TAmburini didn’t at least have motorcycles in the back of their mind. Especially since the original HB1 prototype was built around the remains of a Honda CB750 crashed by Mr. Tamburini.

The reliable, powerful CB750 engine suited Bimota’s mission to a “T”: in the early 1970s, the Japanese manufacturers had definitely sorted their engines and were selling like hotcakes, but handling sometimes bordered on lethal, owing to frames with the approximate stiffness of al dente pasta. Instead of trying to build an entire motorcycle from scratch, Bimota simply took those powerful, reliable engines and fitted them with very few updates to lightweight, stiff frames and wrapped them in sleek, aerodynamic bodywork. They were fast, uncompromising, and very expensive.

Only ten original HB1s were ever made, although the HB2 that followed was nearly mass-produced, with 200 built. It may not be original, but this recreation, or replica, or tribute, or whatever you choose to call it was clearly a labor of love.

The seller also provided links to a few articles that feature the bike here and here that are definitely worth a look as well. It may not be the real thing, but this kind of detailed recreation is alright by me, considering the passion and craftsmanship that are clearly in evidence. Keep in mind that the original Bimotas were basically kit-bikes, especially in their earliest days, and probably into the 1980s and 1990s as well... so this painstaking Bimota HB1 tribute is  probably better-built and much better-finished than the original, and a modern electrical system means it will surely be more reliable. What price perfection? Well the seller is asking $33,000 for this stunning HB1 replica, which seems almost a bargain, considering the work and high-quality components that have gone into it.
