Suzuki Rg500 Gamma
The Suzuki Rg500 Gamma has a top speed of 220 km/h, produces 95 hp and weighs 154 kg. Motoryk rates it 8.5/10.
A Suzuki RG500 Gamma foi introduzida em 1984 como uma réplica legal para uso rodoviário da motocicleta de corrida RG500 Grand Prix da Suzuki, que dominou o Campeonato Mundial de 500cc com pilotos como Barry Sheene e Marco Lucchinelli. Ela apresentava um motor quadrado de quatro tempos derivado diretamente da moto de corrida, tornando-a uma das motocicletas de produção mais exóticas e poderosas de sua época. A produção durou até 1987 e continua sendo muito procurada por colecionadores devido ao seu pedigree de corrida, estrutura leve de alumínio e desempenho bruto de dois tempos.

O que os compradores devem saber
Strong Resale Value
The RG500 Gamma is a highly collectible 2-stroke GP replica, with well-maintained examples regularly fetching $15,000–$30,000+ USD. Values have been climbing steadily as rideable examples become increasingly rare.
Power Valve Maintenance Critical
The SAEC (Suzuki Automatic Exhaust Control) power valves are notorious for seizing if not regularly cleaned and serviced. Neglected valves can cause severe power loss or engine damage, so always verify their condition before buying.
Square Four 2-Stroke Engine
It features a rare 500cc square-four two-stroke engine derived directly from Suzuki's 1970s–80s Grand Prix race bikes, producing around 95 hp in stock form. This exotic layout makes parts scarce and specialist knowledge essential for repairs.
Gerações e especificações por ano
Quadrado original de 500 cc de dois tempos, estrutura de alumínio, garfos antimergulho, carenagem completa, design derivado de corrida.
"A coisa mais próxima de uma bicicleta GP que você poderia comprar."
Nada em 1985 preparou você para aquele quarteto quadrado girando além de 8.000 rpm — a banda de potência bate como um soco no peito e não pede desculpas. Abaixo de 7.000, é bastante dócil, quase enganoso, então as válvulas de potência se abrem e a roda dianteira recebe ideias. A estrutura de alumínio e os garfos antimergulho são genuinamente baseados em corridas, não em linguagem de marketing — essa coisa muda de direção com uma precisão que ainda confunde os pesos médios modernos. Porém, os contras são reais: partidas a frio exigem ritual e paciência, a disciplina da pré-mistura não é negociável e as câmaras de expansão enferrujam por dentro se você a deixar molhada.

Contras
Estilo de carroceria atualizado, configurações de suspensão revisadas, pequenos refinamentos no sistema de carburação e resfriamento introduzidos.
"A melhor produção de dois tempos já construída, mas ela vai morder."
A carroceria da 2ª geração parece mais nítida do que a original e a suspensão revisada realmente fez a diferença no uso em estradas secundárias — menos nervosa no meio da curva do que os primeiros carros. Esse quarteto quadrado grita a 9.500 rpm com uma selvageria que nenhum quatro tempos da época poderia igualar; atinja a banda de potência a 7.500 e é como se alguém tivesse acendido um foguete embaixo de você, 154 kg ou não. O jateamento de carboidratos ainda exige atenção com a temperatura e a altitude, e as partidas a frio são um ritual de asfixia, paciência e palavrões moderados. Os custos operacionais o humilharão: anéis, palhetas, câmaras de expansão e o calcanhar de Aquiles de todos os RG500s, um virabrequim que não perdoa a negligência ou a pré-mistura barata.

Avaliação do comprador usado
"The most exciting road motorcycle of its era, demanding complete commitment."
$18,000-$45,000 usedLet's be straight with you: the RG500 Gamma is a racing motorcycle wearing road bike clothes, and it will remind you of that fact constantly. Those four Mikuni carbs need synchronising religiously, the powervalves seize if ignored, and finding someone who actually knows two-stroke square-fours is increasingly difficult. Budget for a full rebuild before you even think about riding it — gaskets, seals, the lot. Non-negotiable. When it's right, though, nothing from the mid-eighties touches it. That 499cc two-stroke screams to 9,500rpm with a savagery that makes modern sportsbikes feel polite. The chassis is genuinely race-derived — Suzuki didn't dumb it down for road use. It corners with an accuracy that still impresses today. You understand immediately why it dominated production racing. Condition varies wildly in the used market. Most have been thrashed, neglected, or bodged with non-standard exhausts that kill the powerband. Originality commands serious premium now. Walk away from anything with mismatched pipes or mystery wiring. These are appreciating collector machines — buy the best example you can possibly afford.
