“Miguel Angel Galluzzi designed the 900SS just for me” FOR one reason or another, I didn’t ride a motorcycle for a year or so until recently. At least I had a job writing about them, so it wasn’t a total drought. But let me give you the tip, riding beats writing any day. So it felt pretty good to finally push the bike into the sunlight, give it a tub and prepare it for battle. Charge the battery, check the vitals, pump up the tyres. I’ve owned this bike for more than 25 years, the longest period I’ve ever owned anything. I know it better than I know my wife. It’s a 1992-model Ducati 900 Supersport, with the compliance plate stamped September, 1991. I paid top dollar secondhand for the…

ROYAL Enfield built its first motorcycle, powered by a proprietary 239cc single, in Redditch, Worcestershire, in 1901, and its first 350 single, using a Prestwich engine, in 1924. The first 350 Bullet debuted in 1932 with Enfield’s own inclined ‘sloper’ single-cylinder four-stroke engine with exposed valve springs, which was updated to a vertical engine style in 1936. After building both side-valve and OHV 350s for the British army and RAF during WWII, Enfield returned with the redesigned Bullet 350 in 1948 with hydraulic forks, a twin-shock swingarm and an alloy cylinder head. Among Enfield’s customers was the Indian government, which, in 1955, placed an order for 800 Bullet 350s for its police force and army. A joint venture company was established to assemble the bikes initially, then from 1957 to…

I TOOK the just-finished Ducati 175 Super Sport for an enjoyable spin around the quiet lanes of Pennsylvania’s Nockamixon State Park on a warm summer day, followed by a faster fling along the state highway outside. Despite the high compression, the little engine starts easily when warm, but won’t idle since you have to blip the throttle to above 3000rpm to ensure you’re pumping enough oil to lubricate the roller big end and top end of the motor. Having begun my racing career on a valve-spring Ducati 250 Mach 1S, sliding aboard Jeff’s 175 SS was a real trip down memory lane, except the SS felt much smaller. First gear is very low but driving hard in second, the torquey little motor came into its own, accompanied by a glorious…

THE BMW R65 was released in 1978 and sold alongside the existing 600cc, 800cc and 1000cc /7 series twins. Still an OHV, two valves per cylinder, boxer twin, the R65 was otherwise a significant update on the airhead series introduced with the /5s in 1969. The engine was significantly oversquare at 82 x 61.5mm for 650cc, compared with 73.5 x 70.6mm for the 599cc R60/7. This was quite a departure for BMW, given that every other airhead from the 500cc R50/5 to the 1000cc R100RS had the same 70.6mm stroke. Compared with the R60/7, the R65 engine made more power (45hp vs 40hp) at more revs (7250rpm vs 6400rpm). Weight was similar at around 210kg full of fuel, but the R65 was much more nimble with smaller overall dimensions, a…

AS WELL as housing one of the world’s finest collections of historic motorcycles, the Haas Moto Museum also looks to the future by commissioning electric-powered bikes from legendary custom builders like Walt Siegl, Bryan Fuller and, you guessed it, Jay Donovan. Most electric bikes fall into a few broad categories, according to Jay; something futuristic and abstract, or something trying to mimic a classic café racer or modern sports bike. In every case the problem is the same, how to build something cool around a powerplant with the visual appeal of a house brick. “It is enormously challenging to infuse an e-bike with the aesthetics and romance of an internal combustion cycle,” Jay told BikeEXIF on the release of ‘Stingray’ in 2019. “You are deprived of most of the iconic…

SUZUKI’s first 250 debuted as the Colleda twin in the mid-1950s, but was rarely seen outside Japan. The long-stroke 18hp Colleda engine ran on premix fuel and was contained within a pressed-steel chassis typical of the period. The similar T10 followed in the early 1960s, but it was the T20 released in 1965 that set the course for what was to follow. With square 54 x 54mm dimensions for 247cc, the T20’s all-new aluminium-alloy two-stroke vertical twin made 29hp at 7500rpm. Packing a close-ratio six-speed gearbox when most bikes only had four, and weighing in at around 135kg dry, its top speed was an astonishing 150km/h. Making life easy for owners was Suzuki’s Posi-Force lubrication system (later renamed Crankcase Cylinder Injection, or CCI), which negated the need for pre-mixing fuel…

THEY are asking too much,” a familiar voice said down the phone. “I’m going in at 90 thousand, tops.” "Mate, you can afford it. You've always wanted one, now's your chance. Is it any good?" "Oh yeah …" I've known Terry since we went chasing old motorcycles together back in the 1970s. There were still sheds with dusty relics sitting around then, in the days before the public got excited about old stuff and prices flew up like tickets on a Jeff Bezos moon shot. The big mission was to chase down a Vincent rumoured to be sitting on a back verandah in the old soldier settlement of Kentucky in New England. We'd gone out twice already and even found a DJP sidecar adapted to fit a Norton – probably…
