Rieju isn’t an entirely new name in Australia, but their entry into the local adventure bike market is. The new addition to the range, joining the existing ‘MR’ suite of enduro bikes, is the ‘Aventura Rally 307’.

The name is a little long, but the motorcycle itself is anything but, offering compact dimensions, light weight and LAMS-legal performance. Unlike some other small-capacity adventure bikes, the Aventura Rally 307 is biased toward off-road capability over on-road usability. That capability has been tested and proven by Rieju on the Touareg Legend Rally that follows the route of the original Paris-Dakar Rally. Rieju themselves describe the new arrival as a bike that’s “designed for those who dream of new horizons beyond the asphalt”.

Spanish Origins

Rieju’s story, like many others in the motorcycle industry, started with bicycles. In 1934, Luis Riera Carré and Jaime Juanola Farres went into business manufacturing bicycle accessories. The Rieju name (pronounced REE-AY-HOO) was born from the fusion of RIEra and JUanola. Soon after the business started, the Spanish Civil War almost ended it, but Rieju survived, was incorporated in 1942 and offered its first motorcycle – a bicycle with a French clip-on petrol engine – in 1945.

Rieju’s first true motorcycle came in 1953, also powered by a French engine, followed by a scooter at the end of the decade. A switch to licence-built Italian engines followed in the 1960s, but off-road motorcycles didn’t arrive until the 1970s.

The MR designation for Rieju’s off-road models was first used in the 1980s, with exports (to selected European markets) commencing in the 1990s. Progress was steady for the first decade of the New Millennium before the range was completely restructured in 2009. What had been mostly small-capacity models (50cc, 125cc) expanded when Rieju acquired the rights to GasGas’s pre-KTM enduro platform in 2020, showcasing these new, larger models in competition at the ISDE.

Rieju has been in the Australian market since 2021, with Urban Moto Imports handling local distribution. The MR two-stroke enduros have been the sole local offerings, but the booming small-capacity adventure bike market has led to the introduction of the Aventura Rally 307.

Single and Nimble

At the heart of the Aventura Rally 307 is a 293cc single that’s made in China by Loncin and based on a Kawasaki engine, with development and design from Rieju’s HQ in Spain. Breaking with the existing Rieju range, this liquid-cooled engine is a four-stroke. Peak power of 25kW (33.5hp) is claimed to be the highest in the 300cc class, with peak torque of 27Nm.

Electric starting and electronic fuel injection are standard, the radiator has an electric fan, while a 21-litre fuel tank – class leading and around double the capacity of most rivals – allows a claimed range of 500+km.

The gearbox is a six-speed, with a slipper clutch (“anti-rebound” clutch in Rieju speak) and chain final drive. The running gear sits within a sturdy steel spine frame and conventional swingarm. Suspension consists of unbranded 43mm USD forks and a rear monoshock. Travel is a considerable 235mm at each end, with compression and rebound damping up front, and full preload, compression and rebound adjustability at the rear.

The wheel package is made up of 21-inch and 18-inch spoked rims, shod with dual sport tyres (80/100-21 front and 120/80-18 rear). Braking is via a 300mm front wave disc with two-piston caliper, and 240mm rear disc with a single-piston caliper. Switchable dual-channel ABS is standard, allowing riders to exploit that powerful engine on loose surfaces without ABS intervention.

High Tech, High Style

Leading the standard technical features on the Aventura Rally 307 is a colour TFT screen. Evoking the Dakar Rally machines that have driven this bike's spec, the large (7.0-inch) portrait-format screen presents speed and gear position in bold, easy to read numbers, with revs, engine temp and fuel level prominent, too. Minor data (odometer, tripmeters, clock, air temp, etc.) is displayed above and below the main information.

This screen offers a day/night mode and adjustable brightness, with Mirror Link connectivity allowing navigation and advanced vehicle functions to be displayed. LED lighting is used throughout, while offering USB-A and USB-C ports, plus backlit switchgear, is a nice touch and something you associate with larger, more expensive adventure tourers.

As with the tech, styling on the Aventura Rally 307 has been inspired by Dakar Rally machines. A tall, vertical headlight mounts a tall windscreen that’s said to offer decent wind protection at speed on sealed roads, according to UK testing.

Bodywork is stylish and angular, with a long seat that allows substantial fore and aft movement riding solo, as well as accommodating a pillion. Handguards, a sump bash plate and rear luggage rack are all standard.

The sole colour scheme combines black plastics with white decals on the sidecovers and a bold red seat. Rims, hubs and handguards are finished in black, with graphics combining grey, white and red elements.

PRICED TO COMPETE

Pre-orders for the Aventura Rally 307 opened on 8 May, with a limited batch of the first units to reach Australia arriving in June. Introductory pricing of $8,990 ride away is backed by a two-year warranty.

Stylish, powerful and light (137kg dry), the Aventura Rally 307 is made for serious off-road use, but still practical for the road and capable of highway speeds, so it should find a market locally.

On that light weight, even with the 21-litre fuel tank filled, the bike is only around 160kg, which is lower than a CFMOTO 450MT (175kg) or Royal Enfield Himalayan 450 (181kg) with a dry tank.

Those two LAMS-approved adventure bikes are the Rieju’s closest competitors in terms of price, along with Kawasaki’s KLX300 and the Suzuki V-Strom 250X, which was listing for $6,990 at time of writing, but lacks the spec and performance of the Rieju.

Other rivals include the Honda CRF300 Rally, KTM 390 Adventure R and Benelli TRK 251. Moving up in capacity – and price – there’s the Kawasaki KLE500, Honda NX500 and Benelli TRK 502.

A range of accessories for the Aventura Rally 307 include luggage mounts, a sturdier aluminium sump guard and power upgrade kit, as well as apparel.
