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 307 Rally

It runs a 80/100-21 front and a 120/80-18 rear. 15 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.

What we actually found

The Aventura 307 Rally bridges the gap between basic budget trail bikes and high-end rally builds. Built around a rev-happy 293cc DOHC single, it delivers noticeably more punch than a standard 250/300 dual-sport when accelerating out of deep ruts, with the factory rally tower and 20.5-litre tank providing exceptional standalone range. It feels taller and slightly firmer on the road than a plush trail bike, but offers a strong out-of-the-crate package for riders who want Dakar styling and all-day range without spending thousands on aftermarket rally kits.

Pros for green laning

• Punchy 300 single: the 293cc DOHC engine produces 33.5hp and 27Nm, delivering roughly 25% more peak power than a CRF300L for powering through heavy mud and steep ascents.
• Massive 20.5-litre polymer tank: delivers over 300 miles of real-world range, making it a genuine long-distance trail explorer without range anxiety.
• Long-travel suspension setup: 43mm inverted forks provide 235mm of travel front and rear with 280mm of ground clearance and full-size 21"/18" spoked wheels.
• Exceptional standard value: retails at approximately £4,599 while including a rally navigation tower, aluminium sump guard, and handguards as standard.

Cons and limitations

• Top-heavy when completely full: carrying 20.5 litres of fuel raises the centre of gravity noticeably during slow, off-camber trials-style paddling.
• Tall 890mm seat height: the tall bench seat can intimidate shorter riders when trying to touch down in deep, muddy wheel ruts.
• Firm rally saddle: stiff, narrow seat foam prioritises stand-up mobility over all-day motorway comfort on long road transits.
• Smaller dealer network: a smaller UK dealer and spare-parts footprint compared to mainstream Japanese manufacturers.
