How To Ride Dirt
Curated by Malcolm Smith and Barry Higgins for *Motorcyclist magazine*
It may seem uninteresting or even presumptuous for Motorcyclist to tell you how to ride dirt so we called in some experts. OUr dirt professionals are none other than Malcolm Smith and Barry Higgins and here is our first lesson in the series in How To Ride Dirt.
Control. The first and most obvious object of all maneuvers is control. Consider the fact that the rider weighs almost as much as the bike so the movement and distribution of the rider have a significant effect on the behavior of the bike. Where the body is on the bike will become the balance point of the machine. Loading up the front wheel when you meet a chuckhole and applying the front brake will result in a tumble.
If on the other hand, the rider shifts his weight back and goosed the throttle, the acceleration and weight distribution would be put to the rear wheel allowing the front wheel a better chance of clearing the chuckhole.
Benelli 250 Super Sport
Motorcyclist Test by Bob Greene
The bike is a 1973 Benelli 250 Super Sport. It is a single with an overhead valve that seemed to excel in all of the major areas. The bike arrived the day before Bob Greene was going to ride another two stroked two wheeler to the Bonneville Salt Flats for Speed Week. When he sat down to crunch the numbers, the other [unnamed] bike had a three gallon tank with a total range of 105 miles. Well, to make it to the Salt Flats, the bike had one stretch of road where there was 125 miles without gas. Fortunately; the Supersport, which also had a 3 gallon tank with a range of 225 miles! That is 35 mpg vs. 75 mpg!
So it looks like the Supersport was going to be the bike to ride the 700 miles to Wendover, UT - sans a break-in period on this zero-mile machine. The staff at Motorcyclist wished Greene well and proceeded to stick pins into a map where they thought the little bambino would throw in the towel.
Cruising at a steady 70 mph through the night and into the next day the Benelli he referred to as a jeweled watch delivered him without incident. At 400 miles, Bob gave the chain a spritz of Chain Life (chain lube from “back in the day”) but did not have to adjust the chain.
Ride impressions:
- Unless you need to cruise at 80-90 mph this machine is perfect at 70 mph
- The seat "is not davenport" but does an admirable job
- The passenger pegs offered a nice alternative foot position to lengthen time in the saddle
- Short wheelbase of 48 ½ inches - combined with the spartan suspension imparts a quickness of movement both vertically and and laterally -If a bit longer would be better in high winds and choppy pavement
- Alarmingly agile around town and in the mountains and will grind the muffler tip to remind you of gravity
- Speeds - Top Speed 90 mph indicated ""I'd give it an honest 85 mph." - Cruise all you wish at 70 - 75 mph
- "It's a happy engine at all speeds, due to the good balance factor that keeps the vibes at a low level and not the least objectionable."
- 7,132 foot Montgomery pass just outside of Bishop, California was taken at 65 mph likewise for several other similar passes without incident.
When the author arrived at his destination and beat all of the Motorcyclist editors predictions, he conducted a series of routine engine checks including chain, spark plug and oil. This was especially important since the bike had been uncrated at the Motorcyclist offices for this test.
- The electrode on the plug was visually sharp but the gap was a little tight
- The oil level was still crowding the full mark
- Chain tension gave a clue to the 15 hour break in ride
- Header pipe was showing a bit of a blue hue
Weighing more like a 125, this 250 four stroke has a lot going for it. Without downtubes, a forward facing cylinder that has no backside and faces the breeze, roller and ball bearing bottom end, and an engine any mechanic can figure out make the Benelli 250 Super Sport a real winner.

Ray Banicki of Chicago has been a motorcycle anglophile since 1956 when he bought his first machine which was an Ariel Square Four. Although he has owned a Harley and a Yamaha dirt bike, his true passion is Brit bikes. So much so that he is the become the U.S. Representative for the Norton Owners Club of England.
Ray’s 1968 Norton P11 has 52,000 miles under its wheels but it is anything but weary. Each Winter the passionate enthusiast improves his machine between job in his part-time customizing business, Ton-Up Engineering, Ltd. Here is Banicki’s current configuration:
- Black base and gold leaf accents for paint
- Twin mechanical Campagnolo disc brakes up front "Ray says the mechanical setup is sufficient for the street.
- Chemtab hydraulic caliper in the rear
- Borrani wheels
- Dunlop K81 tires
- Betor shocks
- 6 gallon fiberglass tank from Alloy Racing Equipment out of England
- Dual seat intended for a BSA
- Dunstall half fairing
- Ported heads
- T.C. Christensen competition cam
- 10:1 compression ratio up from 7.5:1
- 32mm Amal carbs
- Automotive oil cooler
- Cibe Auto headlight fitted with yellow fog bulb
- License plate and Lucas taillight relocated on the left side "chopper style!"
- Cycle Gard alarm
Like every winter, Ray plans to add a five-speed Qualfie gearbox and hopefully a 750cc alloy cylinder conversion when the lake cools off this Fall. This may mean another English sheep dog for his wife - that’s her hobby!
