購入者が知っておくべきこと
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.
年別の世代と仕様
オリジナルのスクエア4 2ストローク 500cc、アルミフレーム、アンチダイブフォーク、フルフェアリング、レース由来のデザイン。
"買えるGPバイクに一番近いもの。"
1985年には、8,000 rpmを超えて回転するスクエアフォーの回転に備えるものは何もありませんでした。パワーバンドは胸にパンチのように当たり、謝罪はしません。7,000以下では十分おとなしく、ほとんどごまかしのようですが、パワーバルブが割れて開き、フロントホイールにアイデアが浮かびます。アルミニウム製のフレームとアンチダイブフォークは、マーケティング用語ではなく、まさにレースから派生したものです。これは、現代のミドル級選手が今もなお恥ずかしい精度で方向を変えます。ただし、短所は現実です。コールドスタートには儀式と忍耐が必要で、プレミックスの規律は譲れません。また、濡れたまま座らせると膨張室が内側から錆びてしまいます。

ボディワークスタイルの更新、サスペンション設定の改訂、キャブレション、冷却システムの軽微な改良が導入されました。
"史上最高の量産2ストローク、でも彼女は噛み付くだろう。"
Gen 2のボディワークはオリジナルよりもシャープに見え、改良されたサスペンションはバックロードでの使用に実際に違いをもたらしました。初期の車よりもミッドコーナーの緊張が軽減されました。そのスクエア4は、当時の4ストロークにはかなわなかった野蛮さで9,500 rpmまで叫びます。7,500のパワーバンドを叩くと、154キログラムであろうとなかろうと、誰かがあなたの下でロケットに火をつけたようなものです。カーボジェットは、気温や高度によっては依然として注意が必要であり、コールドスタートは窒息と忍耐、そして軽度の冒涜の儀式です。すべてのRG500のリング、リード、エキスパンションチャンバー、アキレス腱、怠慢を許さないクランクシャフト、安価なプレミックスなど、ランニングコストは控えめです。

"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.
