8/10
Holloway Green Lane Score
An approachable twin with genuinely huge range thanks to its twin tanks, agile with partial fuel but noticeably heavier and top-heavy when brimmed. Rider ability, terrain, weather and tyre choice still move the real answer more than the bike alone does.
Four separate scores, not one blended number, so you can see what's actually driving it.

Where the Rieju Aventura 500 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 Rieju Aventura 500 has a 840mm 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 Rieju Aventura 500
It runs a 90/90-21 front and a 150/70-18 rear. 44 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 Rieju Aventura 500 is a purpose-built long-distance overland machine distinguished by its extraordinary twin 20-litre fuel tanks (40 litres total). With partial fuel it behaves much like a standard 500cc twin, approachable, agile, with an easy 840mm seat height and tubeless 21"/18" wheels that handle trail debris cleanly. Fully brimmed, it gives an astonishing 550+ mile range, ideal for multi-day remote routes where petrol stations are non-existent. Carrying that much fuel in wet British mud does demand muscle and smooth throttle control, though.
Pros for green laning
Unmatched 40-litre dual-tank capacity: twin independent 20L tanks give a range of up to 550-600 miles between fill-ups.
Accessible 840mm seat height: a low, narrow seat base gives confident ground reach on off-camber trail stops.
Tubeless 21"/18" spoked wheels: allows full off-road tyre fitment with easy trailside tubeless puncture repairs.
Standard protective equipment: comes with wraparound crash bars, an aluminium sump guard, a radiator grille, and pivoting footpegs.
Cons and limitations
Heavy when fully brimmed: carrying 40 litres of fuel pushes wet weight past 225kg, making slow-speed balance very top-heavy.
Modest 190mm suspension travel: the suspension stroke can blow through on sharp rocky washouts.
Modest 47.5hp twin: an A2-compliant 500cc twin requires revving to maintain high speeds when fully loaded with camping luggage.
Firm dual-tank switchover: managing independent tank balances requires remembering to toggle fuel pumps on long trips.

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.
