Rieju confirms the UK arrival of its latest single-cylinder Aventura Rally 307 adventure bikes
Spanish motorcycle maker Rieju has announced that its new A2-compliant adventure lineup, the Aventura Rally 307 and 307R, will be imported to the United Kingdom. The initial batch of eighty units is set to land in January, with further shipments to follow in the ensuing months after a small head-start batch this month already sold out.
Rieju is better known in the UK for its off-road two-stroke machines than for street bikes. The company has produced motorcycles in Spain since the 1930s, although its road-oriented Aventura 500, a twin that nods to Honda’s CB500, has attracted relatively modest attention in Britain since 2024.
Under the Rally 307 name, the bike uses a 293cc engine paired with a six-speed gearbox featuring a slipper clutch. This setup appears closely related to the powertrain found in the Voge 300 Rally, sharing the same bore and stroke of 78 x 61.2 mm. However, Urban Moto, the UK distributor for Rieju, notes that the 307’s engine has been revised. According to Jamie Masterman, the upper components—piston, cylinder head, camshafts, valves, and both inlet and outlet ports—are different, and the model benefits from a larger airbox and a modified exhaust.
Most of the changes are internal, but Masterman pointed out that you can spot the difference in the cylinder head cover’s shape simply by lifting the fuel tank. This tuning, he says, adds roughly five horsepower and about 1.5 lb-ft of torque to the engine, yielding a claimed 33 hp at 8,500 rpm and around 20 lb-ft of torque (exact rpm for torque not specified).
The Rally 307 features modern chassis and suspension components, including 43 mm upside-down forks at the front and a rear monoshock, with 235 mm of travel on both ends and full adjustability—more than many small-displacement adventure bikes offer. Even the BMW G310GS falls short in fork size, with 41 mm upside-down forks in its setup.
In terms of styling, the Rally 307 borrows cues from its rivals. Its LED headlight arrangement sits above a mask-like windscreen, reminiscent of KTM’s 390 Adventure R. Yet the bike’s overall silhouette, including the tank shape, upturned seat, chassis, and rear swingarm, closely mirrors Honda’s CRF300 Rally.
Rieju is known for generous fuel capacity; the larger Adventure 500 model touts a 621-mile range thanks to twin 20-liter tanks. The Rally 307, by contrast, uses a single 21-liter tank, which Rieju claims provides about 310 miles of range—one of the best figures in the small-adventure class.
Both the standard Rally 307 and the 307R come with a full-color dashboard loaded with features, such as the ability to deactivate rear ABS, an ambient temperature display, and satellite navigation with Mirror Link (compatible with smartphones akin to Android Auto or Apple CarPlay).
Mechanically, there’s no major distinction between the base and R models beyond the appearance package. The 307R wears a red color scheme, an aluminum bash plate, and aggressively knobbly Michelin Tracker tires. Optional upgrades, such as Öhlins components, are available.
Rieju has already established a handful of UK suppliers to stock parts and intends to broaden its dealership network in the coming year. Estimated prices place the standard Rally 307 at around £4,599 and the 307R from £4,999. Pre-orders are open on the Rieju website.
MCN’s take
We’ve come a long way since 2018, the year Itchy Boots uploaded her first vlog and Royal Enfield introduced the Himalayan 411 to the European market. Fast forward seven years, and the market is flooded with affordable, dependable adventure bikes entering from multiple brands.
With a price around £4,500, the Rally 307 sits between the Voge 300 Rally and Enfield’s Himalayan 450 in the value spectrum. Will it stand out enough to carve a niche, or will it blend into a crowded field? That question isn’t easy to answer.
