Rieju 50 Tango (2007-2009): A Pocket-Sized Supermotard With Enduro Roots

Introduction

The Rieju 50 Tango series, produced between 2007 and 2009, represents an intriguing blend of supermotard agility and enduro toughness in a compact 50cc package. Designed for riders seeking a gateway into motorcycle culture or urban commuters wanting a dose of excitement, this Spanish-made machine offers surprising versatility. Let’s dissect what makes this two-stroke standout tick – and why it still turns heads today.

Design & Ergonomics

At first glance, the Tango’s supermotard DNA shines through its aggressive stance. The 2007-2009 models feature a steel perimeter frame that’s both lightweight (94.5-101 kg / 208-223 lbs dry weight) and rigid, wrapped in eye-catching color schemes like Orange/Black and Blue/White. The 840 mm (33.1") seat height might intimidate shorter riders, but the narrow profile helps with footing.

Standout elements include the Paioli inverted front forks (36-37mm diameter) and mono-shock rear suspension – premium hardware for a 50cc machine. The 17-inch wheels on SM variants (130/70 rear, 100/80 front tires) enhance cornering stability, while enduro-oriented models roll on 19-inch front/16-inch rear hoops for off-road capability. Despite its plastic-heavy bodywork, the Tango feels surprisingly robust during sidewalk inspections.

Engine & Performance

Don’t let the 50cc displacement fool you – the liquid-cooled two-stroke single (40.3 x 39mm bore/stroke) delivers characterful performance. The Dell’Orto PHBN 16 carburetor provides crisp throttle response, though cold starts require mastering the kickstarter ritual. With a 6-speed gearbox and port-controlled timing, the engine thrives between 6,000-11,000 RPM.

Top speed? Expect 85-95 km/h (53-59 mph) in derestricted form – enough for city dashes but requiring planning for highway overtakes. The steel/aluminum silencer produces that classic two-stroke buzzsaw wail, though neighbors might appreciate upgrading to a modern expansion chamber. Fuel economy varies wildly with riding style: 2.5-3.5 L/100km (67-84 mpg) from its 5.5-8.4L (1.45-2.22 gal) tank.

Handling & Ride Experience

Throw a leg over the Tango, and the supermotard intentions become clear. The 1,305-1,332 mm (51.4-52.4") wheelbase offers flickable handling, while the 36mm inverted forks handle curb hops with 120mm of travel. The PRS mono-shock system (130mm travel) keeps the rear planted during aggressive cornering – a revelation compared to budget scooters.

Urban warriors will appreciate the 200mm front/rear discs. Bite is adequate for 100kg total mass, though sintered pads from MOTOPARTS.store could enhance feel. Off-road, the enduro variants (19" front wheel, 220mm ground clearance) handle light trails competently, though the 50cc engine struggles in deep mud.

Competition

The 50cc supermotard/enduro segment saw fierce competition during the Tango’s era:

1. Derbi Senda DRD Pro 50:
   Similar two-stroke setup but with 6-speed "Supertran" gearbox. Heavier at 104kg (229 lbs) but better stock suspension for hard enduro use.

2. Aprilia RX 50:
   Italian rival with nearly identical specs but 25mm Dell’Orto carb. More refined power delivery but complex oil injection system.

3. Yamaha DT50X:
   Air-cooled simplicity champion. Lighter (89kg/196 lbs) but down on power (6.5HP vs Tango’s ~9HP derestricted).

The Tango’s edge lies in its modular design – the detachable subframe and wide aftermarket support make it a tinkerer’s delight compared to more proprietary Japanese designs.

Maintenance & Upgrades

Owning a 15-year-old two-stroke requires vigilance but rewards with simplicity:

Critical Maintenance Items
- Carburetor Rebuilds: Clean the Dell’Orto every 3,000 km (1,864 mi). MOTOPARTS.store stocks PHBN 16 rebuild kits.
- Piston Replacements: Two-strokes demand fresh rings every 5,000 km (3,107 mi). Opt for forged pistons if tuning.
- Cooling System: Flush coolant annually – neglected systems risk warping the liquid-cooled cylinder.

Recommended Upgrades
1. Exhaust System: Swap the stock silencer for an aftermarket expansion chamber (+15% power gains).
2. Braided Brake Lines: Improve brake feel on older models.
3. LED Lighting Kit: Modernize visibility for night rides.

Conclusion

The Rieju 50 Tango (2007-2009) remains a compelling choice for riders seeking affordable entry into motorcycle mechanics and spirited urban riding. While newer electric alternatives emerge, the Tango’s analog thrill – the smell of castor oil, the six-speed gearbox ballet, the supermoto slides – delivers an irreplaceable visceral experience. With MOTOPARTS.store’s extensive catalog, keeping these Spanish terriers running strong for another decade becomes not just feasible, but a labor of love.
