Hello everyone.
Honda's air-cooled trail bike, the Honda XR250, and the BAJA (the Japan-market XR250 BAJA / MD30) with its iconic huge twin headlights.
Even years after production ended, off-road fans still talk about it as a bike they would love to own at least once. Yet most of what you read online is near-legendary praise: "it never breaks" and "it will go anywhere".
If you buy one on looks and reputation alone, a rider used to modern bikes may well find more than a few moments of"Hang on, this isn't what I expected...".
So in this post I will set aside the condition of individual used bikes and parts availability, and focus only onthe weaknesses built into the XR250/BAJA at the design stage.
"To love something is to accept its flaws as well."
If, by the end of this post, you think you could enjoy these drawbacks as part of the bike's character, you and an XR should get along for a long time.
The fate of the air-cooled RFVC engine: the trade-off between power and heat
The RFVC engine at the heart of the XR series is a fine design that squeezes good efficiency out of air cooling. By today's standards, though, there are areas where it is clearly being pushed hard.
Honda and air cooling: a philosophy of simplicity
Honda's founder, Soichiro Honda, is known for his strong commitment to air-cooled engines in the 1960s. He insisted on air cooling even for the Honda 1300 small car (launched in 1969), which led to arguments with younger engineers who wanted water cooling.
However, Soichiro Honda stepped down as president in 1973, so he was not directly involved in developing the XR250. My guess is that the XR250 is air-cooled because, without a radiator or water pump, it needs fewer parts and can be kept light and simple (this is my own speculation).
But in today's extreme summer heat, relying on airflow alone for cooling asks the rider to pay a few prices.
Not a fan of town riding in summer: heat soak, the air-cooled weakness
With no cooling fan like a water-cooled engine, the XR struggles when there is no airflow over it.
In summer traffic jams, the engine's heat has nowhere to go andthe engine loses power from heat soak.
The heat you feel while waiting at traffic lights is intense, and it is hard on the oil too.
The hassle of checking oil on a dry-sump engine
The XR uses a dry-sump system, with part of the frame serving as the oil tank.
This keeps the engine compact, butroutine oil checks are a bit of a hassle.
You can't get an accurate reading until you have started the engine, warmed it up for a few minutes and stood the bike upright.
The convenience of just glancing at a sight glass before you set off doesn't exist on the XR.
From town to forest tracks: the awkwardness of a do-it-all bike
The XR250/BAJA is known as a do-anything machine that can go anywhere. Flip that around, though, and it also means a set of compromises: in any given situation it falls short of a modern bike designed specifically for it.
A tall seat and poor reach to the ground, felt at every stop in town
The long suspension that gives it off-road ability becomes a clear drawback in town.
Having to brace yourself on one leg at every set of lights tires you out more than you would expect in stop-and-go traffic.
Especially when you are carrying a backpack from shopping, or when you suddenly have to put a foot down into a rut, the distance to the ground can give you more than a few nervous moments.
High centre of gravity and weight: turning back on a forest track takes nerve
What you least want on a forest-track ride is a U-turn at a dead end.
The XR250 (especially the BAJA) has a high centre of gravity because of its big tank and large headlights, and it feels heavy when manoeuvring at low speed.
Combined with the tall seat, the risk of a standing drop is always there.
To be fair, this applies to off-road bikes in general, so it isn't a drawback unique to the XR.
Comfort... the seat shape and vibration that work against long tours
For XR owners, the hardest part may be the tarmac before you even reach the forest tracks.
The slim seat, shaped for off-road riding, is far too narrow to sit on for long and tends to give you a sore backside.
On top of that, the fine vibration typical of a single-cylinder engine can numb your hands and feet over a few hours of motorway cruising or main-road riding, and leave you tired the next day.
Drawbacks unique to the BAJA: when its character works against it
The huge twin headlights that define the BAJA are its biggest attraction, and at the same time its biggest weakness.
Bright on dark roads, but the lights don't turn with the handlebars
On the BAJA, the headlight assembly is fixed directly to the frame.
In other words,when you turn the handlebars, the huge headlight unit doesn't point where you are going.
Measures such as fitting LED fog lights to the front forks can give you extra peace of mind.
Big damage in a fall: the vulnerability of the huge headlights
Falls are part of off-road riding, but when a BAJA goes down, the damage tends to be bigger.
The light guard that sticks out to the sideshits the ground in a fall.
A fall that would only snap a lever on the lighter standard model risks bending the expensive headlight unit on a BAJA.
Equipment that lags behind modern (water-cooled) rivals
Finally, I should also mention the compromises in convenience and electrics.
A dim headlight and weak electrics (standard XR250)
In contrast to the BAJA, the standard model's headlight is so dim that it gets mocked as a "paper lantern". The charging system also has little spare capacity, so if you fit the accessories many riders now add, such asheated grips, a USB socket and fog lights, you will always be worried about a flat battery.
Hard to carry luggage: a design that assumes a tail bag
The slim, flowing line from the shrouds through the seat to the rear mudguard is one of the XR's strengths, but it isn't suited to carrying luggage.
Unlike recent adventure bikes, there is nowhere to mount side bags neatly, andif you force it, the exhaust heat can melt your bag or the bike can become unstable.
Summary: knowing its weaknesses is part of loving the XR
Compared with today's well-equipped water-cooled bikes, the XR250/BAJA is by no means a comfortable, convenient machine.
- Air-cooled engine: you worry about heat soak in summer and battle vibration on the motorway.
- Seat height and handling: you take care at every set of lights, and a U-turn on a forest track takes nerve.
- The BAJA's character: bright on dark roads, but the lights don't follow you round tight bends, and a fall is risky.
- Compromised equipment: the electrics are weak and carrying luggage takes some ingenuity.
All of these drawbacks are the result of "simplicity (the beauty of air cooling)" and of Honda pushing off-road performance as far as it could at the time.
Who should still choose an XR250/BAJA
If you share the values below, an XR will make a good companion.
- "I want a motorcycle to be a machine, not a household appliance." Someone who understands the luxury of simply enjoying an air-cooled engine without complex systems like water cooling.
- "I enjoy working around inconvenience." Someone who takes pleasure in solving the seat height and luggage problems through riding skill and customisation.
- "I love its one-of-a-kind presence." Someone who has simply fallen for the BAJA's twin headlights or the XR's go-anywhere look.
When choosing a bike, anyone can accept the advantages. However,once you accept the drawbacks and learn to enjoy them as character, the bike becomes something special to you, more than just a tool.
If, after reading this, you think "those inconveniences don't sound so bad", do give the XR world a try. A rich "conversation with the machine" that is hard to find on today's bikes is waiting for you.
