New OEM set of 3 Standard size Piston Rings for the Vire 7, 12 or Vire 6 BVR engines (Bright silver Chromed)

All three are now reccomended in this chrome to prevent rust-seizing, formerly the 2 lower rings supplied were cast iron without chrome, so now you will have lower friction and longer life

I would recommend before fitting, you clean out your old grooves and hone your cylinder.

Compression tests on cylinders with adequate rings is about 120psi because this is a low compression engine (Vire 6 is slightly lower reading)

I would recommend replacing your rings if you had the piston seize hot or from rusting laid-up, or during refurbishing if there are vertical scratches in them where gas could seep through.

Assists reliable quick starting in damp conditions, correct running.

Please Note: Fitting requires cylinder removal

Standard sized pistons have "69.79" stamped on their crowns, I do have 0.5mm oversize pistons ("70.29" but 99% engines are standard

supplied with a fitting sheet to ensure you can fit them easily and without breakage as i show on youtube "vire piston ring"
