Six Times the Fun: 1978 Benelli 750 Sei for Sale

1978 Benelli 750 Sei Red R Side

With motorcycles, packaging is especially important: everything adds weight, and weight is the enemy of performance. In a car, an extra few pounds here or there may not mean much. On a bike, that same weight can win or lose races. When the Japanese introduced their four-cylinder powerplants in the late 60’s and early 70’s, they hit on a nearly perfect formula, a combination of relatively compact dimensions and reliable power that proved virtually unbeatable, once they finally figured out the braking and handling parts of the equation.

Sure, narrow, torquey Ducatis, durable BMW’s, and charismatic Triumphs have their own strengths, but there’s a reason the prototypical UJM features an air-cooled across-the-frame four: it just flat works. So when a manufacturer bucks that trend, they’re clearly making some sort of extravagant statement, and that’s exactly what Benelli was doing when they introduced their six cylinder 750 Sei.

In classic Italian style, “Sei” means “six”. Everything sounds so much cooler in Italian… “Quattroporte”? So exotic… Wait, that just means “four doors.”

The Sei was first introduced in 1972 as a 750cc bike, although it grew to 900cc’s in 1978. With 71hp and limited cornering clearance, it was intended, not as a sportbike, but as a top-of-the-line GT bike, a statement to the Japanese that the Italians could make something just as sophisticated, just as refined. Which they did, reportedly, but copying a Honda four and then grafting on an additional pair of cylinders…

Styling was subdued, aside from the pipe-organ exhaust sticking out the back, it cost a packet to buy and maintain, and it was relatively thirsty. But crack that throttle, and that wail would make you forgive it almost anything.

From the original eBay listing: 1978 Benelli 750 Sei for Sale

I parked this bike in the back of my garage under cover in 1991 due to back problems.  I rode it for 3 years and it never missed a beat.  I am the second owner.  When I got it I got a tune-up, new rear tire and factory fuel line installed.  The crash bar, highway pegs and seat back rack can all be removed easily, there were no modifications to the bike.  Bike is all original with factory tool kit, original seat bar and only 8582 miles.  No dents or dings. Pipes are good..  Factory Metzler front tire will need replaced.  I did not buy a battery to get it going, don’t want to spend time and money to sell it.  The only things that I know that are wrong with the bike are that the clutch is hanging up from sitting (I was told it may release when bike gets running) and the guage cluster is cracked at mounts. (known problem)   If you have any questions please ask and I will answer them to the best of my ability.  This is basically an un-restored beautifully aged Benelli 750Sei with all the original parts.  Bike is sold as is.  Don’t miss this rare opportunity to own this unusal and unique classic bike.  Thank You. 

1978 Benelli 750 Sei Red R Side Engine

Originality is key with these, as finding parts for a rare Italian motorcycle can be difficult. Engine internals and clutch parts can probably be sourced, but bodywork and trim pieces may be virtually unobtainable. This one looks really clean. It just needs a bit of TLC applied to the carbs and a bit of caution before firing it up.

I would, as the seller mentions, bin those crash bars and the backrest/luggage rack at the first opportunity, and probably replace the instrument cluster with a giant, white-faced Veglia tach, but otherwise this looks like a very nice, very complete example of a classic grand touring motorcycle.
