1968 Motobi 250 6 Tiranti L Side Front

This Motobi Sei Tiranti is new to me, so I did a bit of digging. It was a race bike based on the “Sprite” and built by Primo Zanzani, a roadracer and self-taught motorcycle tuner who came onboard Motobi to develop the four-cylinder 250GP bike and later race bikes based on the egg-shaped Motobi single, helping them earn the 250cc Junior title in 1966, 1967, and 1969.

“Sei Tiranti” refers to the six head studs on the later model homologation bikes that provided additional strength versus the street Motobi’s four head studs that allowed for higher compression and more revs as they chased after more power.

The race bikes were pretty far from the street bikes in every way allowed by the rules in this class. The bikes often bore only a superficial resemblance to the street bikes on which they were supposedly based and included sand-cast cases along with many other trick parts. The bike weighs in at just 223lbs dry, making for pretty good performance when combined with the 33hp and 5-speed box.

Motobi was originally known as Moto “B” Pesaro for founder Giuseppe Benelli and their home province of Pesaro, the name later was shortened to Motobi.

From the original eBay listing: 1968 Motobi 250 Sei Tiranti for Sale

Have a look first at this video of the history of Mr. Primo Zanzani…..his bikes won over 500 races in the 50s and 60s. This racing motorbike, belonging to the history of the racing motorbikes, has been hand built fully by him in person. Fully original in any single parts. Very very rare bike. last one has been sold in Japan for 95.000 euro. Immensive collectionist value.
Visible in our museum in Fano.

Recently restored and fully rebuilt by Mr. Zanzani, still alive and living in Pesaro.

The original listing is found on, but the bike is currently in Fano, a province of Pesaro, very near where it was born. Interestingly, this should be a very authentic rebuild, since Primo Zanzani is still very much alive and running his family business, as well as producing race replicas that appear to be accurate in every detail.

The classified listing states the price as £30,000 which as of today equates to about $47,000, which is some serious change for a motorcycle of any sort, although the seller helpfully cites that previous examples have sold for even more.

I’m very new to Motobi, so if any of our readers can enlighten me further, I’m happy to hear from you!
