Arias 96mm 12.5:1 piston sets, recently re-designed specifically for the TR1. The valve cut-aways are deep enough to afford ample clearance for our wildest cams. A "bare" kit: you provide your own machine work and you must set (if necessary) the ring-end gaps.
Please read the information below the pictures on the page "1065." It could be important. Sometimes I have several sets in stock, both bare and as part of the kits described below. Lately, I have not been able to keep them on hand: I open an incoming box of pistons, repackage them, and ship them out that same day or the next. If you want (or need) these pistons, I urge you to order them now and just wait for the next available. Recently, I had a whole batch sold a full month before they arrived here. I sell these domestically (for the 920 and 1000 Viragos), and in the Eastern Hemisphere (for the TR1 and its variants).
What you get: two pistons, two sets of rings, two pins, four clips, no gaskets. This gives you a full-liter (1004cc) twin with a significant compression ratio -- use the highest octane fuel that the station carries.
Keep in mind that these are forged -- they require greater clearance than cast. They will be noisy until the engine reaches operating temperature.
