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.
La Suzuki RG500 Gamma se presentó en 1984 como una réplica legal de la moto de carreras RG500 Grand Prix de Suzuki, que había dominado el Campeonato del Mundo de 500 cc con pilotos como Barry Sheene y Marco Lucchinelli. Tenía un motor de cuatro tiempos y cuatro cilindros derivado directamente de la moto de carreras, lo que la convertía en una de las motocicletas de producción más exóticas y potentes de su época. La producción duró hasta 1987, y sigue siendo muy solicitada por los coleccionistas debido a su pedigrí propio de las carreras, su ligero cuadro de aluminio y su impecable rendimiento en dos tiempos.

Lo que los compradores deben 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.
Generaciones y especificaciones por año
Cuatro cuadrados originales de 500 cc y dos tiempos, marco de aluminio, horquillas antibuceo, carenado completo, diseño derivado de las carreras.
"Lo más parecido a una moto GP que puedes comprar."
En 1985 no había nada que te preparara para esos cuatro cuadrados que giraban a más de 8.000 rpm: la banda de potencia golpea como un puñetazo en el pecho y no se disculpa. Por debajo de las 7000 es bastante dócil, casi engañoso, y luego las válvulas de potencia se abren de golpe y la rueda delantera se pone manos a la obra. El cuadro de aluminio y las horquillas antibuceo son genuinamente de carreras, no de lenguaje comercial. Esta máquina cambia de dirección con una precisión que todavía avergüenza a los pesos medianos modernos. Sin embargo, las desventajas son reales: los arranques en frío requieren ritual y paciencia, la disciplina con la premezcla no es negociable y las cámaras de expansión se oxidan por dentro si la dejas reposar mojada.
Pros
Contras
Se ha actualizado el estilo de la carrocería, se han revisado los ajustes de la suspensión y se han introducido pequeñas mejoras en los sistemas de refrigeración y carburación.
"La mejor producción de dos tiempos jamás construida, pero morderá."
La carrocería de la segunda generación tiene un aspecto más nítido que la original y la suspensión revisada marcó la diferencia en el uso en carretera, ya que fue menos nerviosa en la mitad de la curva que los primeros coches. Ese cuadrangular grita a 9.500 rpm con un salvajismo que ningún vehículo de cuatro tiempos de la época podía igualar; si llegas a la banda de potencia a 7.500, es como si alguien hubiera disparado un cohete por debajo de ti, con 154 kg o no. La inyección de carbohidratos sigue exigiendo atención con la temperatura y la altitud, y arrancar en frío es un ritual de asfixia, paciencia y blasfemias leves. Los costes de mantenimiento le harán perder peso: aros, lengüetas, cámaras de expansión y el talón de Aquiles de todos los RG500: un cigüeñal que no perdona el descuido ni la premezcla barata.

Reseña de un 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.
