Hy Guys,

does anyone know the con-rod length of a GasGas EC 250?

As far as I know the rod has not been changed from '97 till today.

GG 250 rod( same with 200 & 300) is a honda cr250 rod(84-01); la sleeve calls this at 125.3mm, but vesrah(oem) calls it at 126; i prefer to use an ims "pro series" rod kit, due to an improved lower bearing/just out of curiosity, i measured a couple "used" rods laying around here; the ims rod measured at 125.3mm vs vesrah rod at 125.5mm; the vesrah rod is less expensive and i would assume a high standard of "japanese" quality,...
i know, kind of "long winded"(again!) jack

Thanks Jack,

it's just for calculating msv. But interesting to hear of your experiences with the different rods.

Wouldn't that .3mm difference cause havic with compression? The piston sitting .2mm farther down the hole can't have any beneficial effects unless you are lookng for less compression.
