8/10
Holloway Green Lane Score
The friendliest enduro bike you can buy: very light, lower than a race enduro, with soft two-stroke power and oil injection so there's no mixing. Rider ability, terrain, weather and tyre choice still move the real answer more than the bike alone does.

Where the Beta Xtrainer 300 sits
Wet weight against ground clearance for every bike in the finder that publishes both. Light and tall, top left, is where the easiest green lane bikes sit. Tap a dot to open that bike.
Figures are manufacturer claims. Clearance is measured differently by different makers, so treat small gaps as a draw.
Will your feet reach?
The Beta Xtrainer 300 has a 910mm seat. Enter your inside leg for a rough idea of how much foot you'll get down when stopped.
A rough guide only. A wide seat needs more leg than a narrow one, the suspension settles 20 to 40mm under you, and boots add a little. Many bikes offer a low seat or lowering link. Sit on one before you buy.
Range against similar bikes
Real-world range from tank size and typical economy, against the bikes closest to it in weight and type. Out on the lanes, fuel stops are often further apart than on a road ride.
Range only. Hard off-road riding and headwinds use more fuel, so plan fuel stops with margin.
Tyres that fit the Beta Xtrainer 300
It runs a 80/100-21 front and a 140/80-18 rear. 31 tyres in our Tyre Finder are made in at least one of those sizes, ranked by green lane score.
Sizes are for the standard UK model and can change between model years. Check the size on your own tyre sidewall, and ask your dealer before fitting a different size. Our size lists come from maker and retailer listings and can miss sizes, so a tyre shown for one end may still be made in your other size. Check the maker's size chart.
The Xtrainer is Beta's answer to riders who want enduro-level lightness without race-bike aggression. At 99kg dry with a 910mm seat, it's the lightest bike in our Bike Finder and lower than most enduros. Its 293cc two-stroke is tuned for soft, torquey power that finds grip on wet roots and rocky steps, and electronic oil injection means you fill the oil tank rather than mixing two-stroke oil into every tank of fuel. Dirt Rider's 2025 dyno test measured 31.5hp at the rear wheel.
Pros for green laning
Lightest bike in our Bike Finder: Beta quotes 99kg dry.
Electronic oil injection: no premixing fuel, unlike most two-strokes.
Soft, torquey power that's forgiving on slippery, technical ground.
910mm seat is low for an enduro, and it's far cheaper than a race enduro.
Cons and limitations
Two-stroke top ends need servicing more often than a four-stroke trail bike.
Not happy at speed on main roads; best when your lanes are close to home.
Small 8.8L tank and a carburettor rather than fuel injection.
Power-to-weight means it needs a full A licence.
Based on manufacturer specifications and independent motorcycle press reviews.
Remember: a rank here assumes reasonable stock tyres and a competent rider in decent conditions. The right tyres, or the wrong weather, can move a lane from easy to genuinely hard regardless of what bike you're on. Check a lane's own difficulty and hazards on the map before you go, don't rely on a bike score alone.
