Does anyone know where I can source a set of piston rings to fit a Honda RTL 250 (1986 - Drum Brake) .I have exhausted all my normal sources so getting desperate !!!!!

You might have to 'bite the bullet' and buy a piston complete, have seen them on e-bay £300 squidish. From recollection aftermarket pistons made by omega, doubt wether thier rings would fit a geniune piston though....so probably a case of payup and look big for a complete piston assembly.

Old ebay listing here http://www.ebay.co.u...5-/130555431621 , it's a long shot but he might have something left over.

Not sure of the piston diameter but there's a Honda piston size chart here http://www.4-stroke....ston-size-chart , maybes the piston could be adapted to take rings from a different model if they were taller.

I don't know much about these engines, only the TL/XL/CB 125 motors, did the RTL have a Nikasil bore? Just asking as I have read that you can't rebore them. Also, I believe that rings for Nikasil bores are not of the same material as rings for cast bores.

Thanks for the feedback.....Pretty much where you guy's have said. Have been offered a Omega piston and rings (yes, £300!), but have decided to polish barrel and rebuild with new valve stem seals and see how it runs!! Have been told there is an internet site in Spain that sells them but I cannot find it and my Spanish isn't great!!!! Jerry

ATC 200 and 250 pistons are pretty much the same...look ,, you will find..

what a brrilliant site, great info

have you tried a chinese piston/rings there are a load about and some sites even give dimensions ect.

good luck
