Tornou-se notável nos mercados europeus como uma porta de entrada acessível e acessível para o motociclismo off-road, em conformidade com as restrições de licença AM para jovens de 16 anos em muitos países da UE.

O que os compradores devem saber

⚙️

Minarelli AM6 Engine

The MRT 50 uses the widely respected Minarelli AM6 two-stroke engine, meaning spare parts and performance upgrades are cheap and readily available across Europe. This makes maintenance far easier than bikes with proprietary engines.

⚠️

Watch the Cooling System

The liquid-cooled AM6 variant is prone to coolant leaks and water pump wear if not regularly serviced — always check for overheating signs or milky residue before buying used. A neglected cooling system can lead to costly piston and cylinder damage.

💶

Decent Resale Retention

The Rieju MRT 50 holds its value reasonably well in the 50cc trials/enduro segment due to its sporty image and Spanish build quality, which is generally regarded as a step above budget Chinese competitors. Buying used in good condition is relatively safe as an investment.

Gerações e especificações por ano

2000–2005 Gen 1

O MRT 50 original foi introduzido com motor Minarelli AM6, estilo motard inspirado em testes e estrutura de aço.

7.2/10

"Arma urbana fina e poderosa com limites frustrantes de 50 cc."

A MRT 50 é mais alta e mais estreita do que você esperaria de uma bicicleta para estudantes restritos — a altura do assento de 920 mm e o DNA de testes proporcionam uma postura surpreendentemente firme e inspiradora de confiança em curvas urbanas estreitas. O motor AM6 é a verdadeira salvação aqui; é uma unidade comprovada e ajustável que funciona de forma limpa a partir de cerca de 4.000 rpm e responde bem a uma atualização de tubos e palhetas, se as leis locais permitirem. A 45 km/h restritos, você será comido vivo em qualquer estrada com tráfego em movimento, e o escapamento de estoque será deliberadamente estrangulado a ponto de causar constrangimento. A estrutura de aço parece superconstruída para 50, o que funciona a seu favor em estradas mais acidentadas, mas o hardware de frenagem econômico da era Grimeca precisa de uma atualização quase imediata se você planeja pedalar com força.

Prós

+Motor AM6 altamente ajustável
+Geometria de manuseio alta e confiante
+Estrutura de aço leve absorve punição
+Posição de pilotagem motarda genuína

Contras

Restrição de 45 km/h mata a usabilidade
Os freios padrão parecem perigosamente macios
Plásticos racham após pequenas derrubadas
Melhor para: Jovens de 16 anos aprendendo a pedalar de verdade Ignore se: Você precisa de velocidade real na estrada
2006–2010 Gen 2

Carroçaria revisada, componentes de suspensão atualizados, ergonomia refinada, motor AM6 contínuo de dois tempos.

expand_more
7.4/10

"Pequena arma de teste desajeitada que soca acima do deslocamento."

A Gen 2 MRT 50 é uma bicicleta de testes para iniciantes devidamente classificada que realmente ensina algo: a suspensão revisada absorve terrenos rochosos melhor do que a maioria dos rivais de 50 cc, e o assento mais alto de 920 mm força você a ficar na posição correta desde o primeiro dia. O motor AM6 é uma quantidade conhecida: ajustável, com peças confiáveis em todos os lugares, mas é asmático abaixo de 4.000 rpm e você usará a embreagem constantemente nas seções técnicas. Essa carroceria revisada é legitimamente melhor — cintura mais fina, mais fácil de segurar com os joelhos — mas a qualidade do plástico ainda parece ter sido proveniente de um catálogo de móveis de jardim. Com 68 kg, é leve o suficiente para que um adolescente possa manipulá-lo em uma seção de testes, mas competidores sérios do clube o superarão em uma temporada e começarão a observar os 125.

Prós

+Suspensão revisada, visivelmente mais compatível
+Motor AM6: peças universais baratas, ajustáveis
+A ergonomia fina recompensa a técnica de testes adequada
+Leve o suficiente para ser manuseado em caso de acidente

Contras

A banda de potência chega tarde, estreita
Painéis de carroçaria de plástico baratos e frágeis
O limite máximo de 45 km/h limita o uso versátil
Melhor para: Princípios básicos de testes de aprendizagem para jovens iniciantes Ignore se: Competindo seriamente além da classe de novatos
2011–2016 Gen 3

Gráficos e plásticos atualizados, sistema de frenagem aprimorado, pequenos refinamentos no chassi, conformidade com Euro 2.

expand_more
2017–2023 Gen 4

Atualizações de motor compatíveis com Euro 4, sistema de escape revisado, estilo e instrumentação modernizados da carroceria.

Urban commuters wanting real character, not plasticky

"A gem when clean, but buy carefully or regret it."

$1,500-$3,200 used

The Rieju MRT 50 is a Spanish-built trials-influenced supermoto that punches above its 50cc weight class in terms of looks and chassis quality. The frame is genuinely well-engineered, handling is razor-sharp, and the upright ergonomics make it genuinely fun to hustle through tight urban traffic. It feels more serious than your average restricted learner machine, and that's legitimately earned. Here's the reality check though — used examples are a lottery. These bikes attract young riders who thrash them hard, and the 50cc two-stroke engine is fragile when neglected. Always check for seized components, dodgy reed valves, and whether the previous owner ever bothered mixing oil properly. Parts availability is patchy outside Spain, so factor that into your budget. If you find a clean, low-mileage example with service history, you've found something worth having. If it's tatty and cheap, walk away — repairs will eat you alive.
