Benelli 900 Sei

Sold at the time as Italian Alternative’, this superbike from the 1970s offers something radically for the classic bike connoisseur.

In Benelli stole a march on the of the motorcycling world when launched the first production bike, the 750 Sei. A few years they brought its big brother to the UK, and RC Phil Colin was so smitten by the that he just had to own one. bought his 900 Sei second-hand in 1985 and then didn’t fire it up for a quarter of a century!

Back in the Benelli’s range were around a version of the Honda four-cylinder engine. To create the 750 added an extra set of cylinders, and the alternator behind the block of leaving it hanging on the end of the crankshaft. kept the six-cylinder 750 quite and contributed towards its tidy-looking, appearance.

Stiff suspension, a chassis and the smooth motor that the 750 developed a reputation for taut and responsive, although not fast.

The 900 was by boring and stroking the motor to 60mm by 53.4mm and thus at 8400rpm. Three 24mm carbs fed fuel to the 906cc, engine which used two per cylinder. Benelli tweaked the of the 900 to address some of the teething encountered on the 750, and one of the benefits was a in weight.

The 900 weighed just 220kg dry some 20kg less Honda’s four cylinder which was current at the time.

The 900 featured a fabulous Siltenium exhaust system which rot better than the straight system fitted to the 750. novelties included the duplex drive chain (now expensive to replace, and owners converting back to simplex — modern chains are than up to the job of handling the power), alloy wheels and the moulded panels which concealed the petrol tank. Removing the bodywork to access the tank is one of those jobs which can grown men to weep quietly in

Where the 900 was with its braking, from Brembo discs featuring calipers, and with its handling. The firm rear damping it feel much more than the typically soft UJM and meant that it was far easier to fast on smaller roads most four-cylinder bikes on the It was reasonably stable at high and fitting modern shocks helps — although the end with its 35mm forks seem somewhat skinny by standards.

Even though the Sei was slower on than the six-cylinder competition Honda and Kawasaki, in real it could more than up with a CBX or Z1300 on A-roads. Cycle Weekly said ‘its motor does not the technical excellence of several multis, but the Benelli’s handling, holding and braking more make up for its shortcomings.’

A 900 Sei would happily at 70mph to 90mph, no It covered a standing quarter in 13.3 seconds, with a velocity of 99.8mph. In normal use the 900 Sei returned around 40mpg, this could drop to 32 extreme provocation.

These most owners get around ‘dropping to about 43 if driven says Chris Grigson who the Benelli Club magazine. of the time reckoned that the 900 Sei far better than Japanese sticks to the road like to flypaper and can brake as if it has been run a wall.’

However, there was an inevitable premium for this interesting and Benelli customers paid a price for unremarkable top speed and 125mph was realistically the best you expect from the 900, and it was noisy and somewhat ragged to Honda’s highly refined engine.

The Sei also suffered some other typical problems including an unreliable restricted foot space, forks, slipping clutches and oil seepage around the cylinder The bikes got better (and faster) with later and the initially under-specified alternator was replaced.

The Sei is also often to Laverda’s triples but the two riding are radically different. The Sei feels and free-revving, lacking the low-down of a Jota. The Benelli is lighter on its (and lighter overall) the Laverda, but its engine feels like a Japanese machine a Continental one.

Less torque rewards riders who are to twist the grip — but lads should be warned; the doesn’t have a massive of ground clearance and sparks fly on tight corners.

In total built some 3200 of the 750 but these weren’t sold in — even so, there are 750s than 900s in the club. The 900s can attract big at auction. In 2010 in the USA, one low mileage 900 Sei sold for $18,000 another, higher mileage was up for grabs at $11,000. They are usually offered for sale on the mainland and one started bidding in 2011 at $13,500 USD.

A 900 was offered for sale in Switzerland at the end of for Ј11,500.

However, reasonably-priced do come up for sale occasionally. A 900 was sold in the UK at Bonhams auction in 2011 for Ј5750. It had been restored and came with a MoT plus an assortment of spares.

So are comparable with Laverda 3Cs and the — if you can make your at the right moment.

Some of the 900s were made production ceased in 1985 which happens to be when Colin bought his own 900 for Ј600. It was years old and had covered 18,000 The Sei was ‘well used’ and ‘in of a lot of work to make it nice’.

So Phil set about him with the and reconditioned or replaced ‘absolutely to do with the chassis. This ‘every bearing and seal’ powdercoating, rebuilding the forks and arm, a complete new exhaust and pipes, seat, wheels, carbs, chain and sprockets but not, you’ll be entertained to anything at all in the engine department. The needed no work whatsoever!

As you can tell from its condition, the Sei has been hardly in the 25 years since it was reconditioned. In it hadn’t run for so long that couldn’t really remember it sounded like. When he got it again recently, he was startled to it.

‘The first time it after 25 years — I had the sound! It’s amazingly for an old motorcycle’. Now the Sei is used for occasional on sunny summer days. fancies cleaning up the engine ‘when I first bought it I afford to have the engine blasted; soda-blast treatment give them a super finish.’ However, Phil’s not on modifying the Benelli; ‘I’m a bit of a and like the way it was made, although it benefit from a modern with more control advance.’

Phil likes the Sei just the way it is. He that if you’ve been by the idea of a Sei then you shouldn’t pay too attention to its detractors.

‘Just buy it and the critics and the pub experts. Just every minute!’
