Honda S600 S800 Chain Tensioner Assy - Genuine NOS Part
S078 ガレージ蔵出し品 貴重 ホンダ 純正 当時物 絶版品 ★ S600 S800 チェーン テンショナー Assy ★ 旧車部品 ストックパーツに

This is a genuine old-stock (NOS) chain tensioner assembly for the Honda S600/S800, sourced from a long-time Honda dealer and service shop's warehouse stock in northern Japan. The seller states it was found in a box labeled S800 but cannot confirm with certainty whether it fits the S600 or S800 specifically, so buyers should check compatibility against the listing photos before bidding. The part measures approximately 13cm wide, 12cm tall, and 8cm deep. Only the item shown in the photos is included; no other hardware or documentation is mentioned. The seller notes this is a rare part rarely seen for sale, suitable for restoration, maintenance, or as a stock spare for S600/S800 owners.
Seller states no notable scratches or dirt, though the description also mentions light surface soiling and natural wear from long-term storage typical of an old genuine part.
Shipping: Ships via Sagawa, Yamato, or Japan Post only, with the carrier chosen by the seller based on size and weight. Packing size is listed as 60 (a small parcel size).
Ships from Yamanashi, Japan, to our Osaka warehouse and on to Pomona.
