Turbine Core II

i'm not riding ring-dings anymore, so don't have current experience. but..., my old KDX220 wore one well. it's quiet (quieter in think, than the stocker). and it gave the bike a bit more urge everywhere. and it's quiet.

i modified a used one from a '98 KX250 to fit an '87 KDX200, and same results. it's quiet. it gave the bike a bit more from one end to the other. and it's quiet.

and the quality is unquestionable. AND!!!..., it's spark arrested.

don't discount the quiet part. expecially if you're trail riding. we have a lot of shared trails here in the great PNW, and will occasionally run into hikers. quiet keeps 'em grinning (or at least, not frowning so hard).
