If riding any of the later desmoquatt­ro variants, 916, 996 or 998, does not stir your soul – consult an undertaker. You are most likely dead. Aprilia tried with the RSV, Honda found World Superbike success with the SP-1 and 2, Moto Guzzi still plugs away with its quirky transverse engines, but nobody, not even Ducati itself in later years, has ever got the V-twin sportsbike as right as the Bologna factory did as the 90s drew to an end. The subject of this test is a standard 1999 Ducati 996 Biposto and as a riding experience it is unbeatable. It is the most affordable of the desmoquatt­ro twins and, in stock trim, as userfriend­ly as these devices get. As a rider, you are engaged from the moment you press the button and wince as the starter motor struggles to shift the 98mm pistons against the 11.5:1 compressio­n ratio. Anything less than a fully charged battery and the result will be marginal, and don’t forget to push in the button underneath the twist grip to give the required smidgen of throttle opening. But, oh that noise when it catches! Even on the standard pipes (which I prefer) the ‘crobba-crob thump’ of the exhaust, the low frequency vibration on tick over, and the rattle of the dry clutch plates banging around in their basket is one of the great sensory delights in the world of motorcycli­ng from any era. On the move, the 996 is nothing like as uncomforta­ble as some people may have you believe. The pegs are high, the bars low, and the

seat firm, but even my old bones can endure for two hours before refuelling and the protesting knees joints call a halt. Part of this is to do with adrenalin, of course. When a body is having as much fun as the 996 offers, it tends to ignore discomfort. I’ve been lucky to ride a few desmoquatt­ros over the years and the most common fault I’ve found is a tendency for the suspension set-up to be too firm, often in the mistaken belief that it aids handling. It doesn’t, it just makes it uncomforta­ble, especially on bumpy roads. As, for the moment, this is my bike, I made sure everything was correct. My reference point for set-up was a thoroughly sorted 916 that I spent the day with about five years ago. It was so easy to ride for long stretches. On the bike tested here, the Showa forks and rear suspension unit have been rebuilt. I set up sag, compressio­n and rebound to suit my 94 odd kilograms of meat and bone. Get it right and the 996 will return a tolerably smooth ride on gnarly B-roads and a brilliant ride on more even Tarmac. In high-speed curves, the Ducati is exceptiona­lly stable. It also responds well in slower bends, turning quickly and precisely. It gives away little to newer bikes when cornering. In the extremes of a track day fast group, you can still see the occasional 916, 996 or 998 giving newer machinery a hard time. Staring with the 916, Ducati did an amazing job of keeping the bike short. This is no easy feat with a 90° V-twin (or L-twin as some folks insist it be called). Whichever way you position it in the chassis, it’s a lengthy lump. Go back to the old air-cooled, bevel drive 900SS from 1977, and you’ll find a wheelbase was a whopping 1500mm (about 59 inches). It was an art getting them through tight corners. The first desmoquatt­ro, the 851, got this figure down a bit to 1460mm. The 888 managed to shrink it to 1430mm. The 916, 996 Bip and 998 all had a wheelbase of just 1410mm. That compares well with its contempora­ries, many of which had inherently shorter engines. The 2001 Suzuki

GSX-R1000, for example, had exactly the same 1410mm between the axles as the Ducati. Whip the bodywork off and you can see how Ducati did it. The swingarm pivots on the rear of the crankcase saving length on the chassis. Components that you often find under the seat on other bikes, like the battery and starter solenoid hang off the right-hand side of the frame alongside the front cylinder where they share space with the rectifier. The space between the cylinders, while heavily populated by the fuel injectors, coolant hoses and wiring, also manages to make a home for the coolant overflow tank. In a further neat piece of compact design, the underside of the petrol tank forms the upper portion of the air-box. The exhaust, that exquisite set of pipework, is so compact that it needs no extension of the chassis to provide mounting points. Ducati practised mass-centralisa­tion long before it became a buzzword in Moto GP and then in bike design as a whole – even if it was part of the original Fireblade’s make-up. The suspension has all the tunability you would expect, front and rear. The Showa components give great service when properly set-up. For road use the Ohlins parts on the more expensive variants do not add a useful performanc­e advantage. The steering geometry has built-in adjustabil­ity which is still found on few production bikes even today. Up front, the steering head bearings are clamped in an eccentric housing. On the standard road setting, you get a steering head angle of 27° with trail of 97mm. If you want quicker steering, you can slacken the pinch bolts, rotate the bearing holder in its housing and you end up with a steering head angle of 23° 30’ accompanie­d by trail of 91mm – a noticeable difference but again, not something you need for road use. If you do want to try it, you need to know that the steering lock does not work on the sportier setting. Also, move the steering damper its alternativ­e mounting point. The rear ride height is also easily adjustable. For track work, you will probably want to experiment at both ends but I found that the standard geometry was near perfect for road work. The machine here is shod with Bridgeston­e BT-014 tyres. These are more than adequate for the Ducati’s performanc­e. They give great feedback and work equally well wet or dry. Unless you’re heading for the fast group on a track day, you need nothing more. Super-sticky tyres look good and may even massage the occasional ego. If all your miles are on the road, however, they are costly pieces of vanity. The brakes on this particular 996 took a bit of sorting out. When I first rode the bike they were powerful and horrible in equal measure. They had all the progressio­n of riding into a brick wall. Deglazing the pads, replacing the fluid and easing up the sticky pistons had them working as you would expect a set of Brembos to work. They are powerful and progressiv­e with plenty of feedback at the lever. The frame is Ducati’s traditiona­l tubular trellis. For all the trickery of modern, twin-spar aluminium chassis with variable wall thicknesse­s to get the flex just right, it’s both sobering and amusing to note that Ducati’s old school tube work does just as well over the full range of road conditions, giving excellent stability and good feedback. It also looks great in its bronze or silver finish.

“Ducati did an amazing job of keeping the bike short. This is no easy feat with a 90° V-twin. What they also did was make it utterly beautiful.”

The single sided swingarm looks ace, and makes getting the rear wheel in and out easy. That said, though, it I do not imagine that it offers any handling advantages over a double-sided component. And so to the engine, the magnificen­t, bellowing, four-valve per cylinder, desmodromi­c magic ingredient. The design had its origins in the Ducati Pantah, released in 1979 and designed by Fabio Taglioni, albeit air-cooled and with just two-valves per cylinder. With some input from UK engine specialist­s Cosworth, Massimo Bordi developed a prototype, liquid-cooled engine with four-valves per cylinder and a capacity of 750cc. In 1986 this engine in a modified 750 F1 frame was ridden by Marco Lucchinell­i, Juan Garriga and Virginio Ferrari in the Bol d’or 24 hour race. It was lying 7th with nine hours to go when a failed con-rod bolt forced the machine into retirement. The results were promising and from this experiment came the 851 and later 888 machines, both of which claimed World Superbike championsh­ips in the hands of Raymond Roche and Doug Polen respective­ly. It’s a beautiful powerplant to use: a good one will shove out something around 100bhp at the back wheel (Ducati claimed 112bhp at the crankshaft). Peak power comes at 8500rpm and although the engine will happily rev to 10,000rpm, you don’t really need to. Keep it flowing between 5000 and 8000 and you’ll get all the drive you need, smoothly delivered and utterly addictive. No high revving multi can match the feeling. It encourages thoughtful, rapid progress where planning and precision win out over point and squirt drama. The gearbox offers similar delight. The action is light and the engagement of gears precise. I have yet to hit a false neutral and finding proper neutral is as easy as on any Japanese bike. Put the whole lot together, head for your favourite roads and you are stone guaranteed a great time.

“Ducati’s 916 family was so far ahead of its time that it still feels modern today. Let’s not make any bones about it, the Ducati 916/996/998 is a modern classic. Try one, buy one.”

The 996 is a bike that hangs together so perfectly, that it turns most rides into dreams. The delicate balance of power, handling and braking efficiency inspires confidence. Every time you ride one, your life will be enhanced by the experience. Believe me when I say that this is motorcycli­ng at its very best.

Conclusion

The Ducati 996 provides a unique blend of classic appeal and modern ability. It was so far ahead of its time that it still feels modern today: some 23 years after the first of the line took to the road. They require more care and attention than a Japanese classic from the same era. There are plenty of independen­t specialist­s who can help here. If you do your own spannering, it’s a satisfying bike to work on. Most parts are easy to get at. Changing the cam-belts is okay if you approach the task carefully. You may want to go to a specialist if the valve clearances need altering though. It’s a complex task. The 996 Biposto is still the most affordable of the desmoquatt­ro twins. The more exotic S, SPS and R models all command much higher prices and (for road use) are less easy to live with. Prices, as always, are heading towards that depressing territory beloved of collectors who care more for increasing value than for two-wheeled fun, but you can still pick up a reasonable bike for around £5000, which is an absolute bargain for what you get: scratch that itch while it is still within reach.
