Maintenance & Technical > KX500 Original
Connecting Rods (Choice and Why)
3Razors:
I like the Wiseco piston for the KX500, LT500, or a custom banshee setup with ALOT of mods. It depends on the bike but for most stock to mild mod bikes I prefer a oem cast piston because you can set the tolerances closer and when maintained properly you get more life out of them over forged.

My only experience with Wiseco was negitive. I had a '82 RM125, bought it used with an overbored Wiseco piston, blew the piston,overbored 2nd over, blew that piston after about 20 hrs. Broken skirt both times. Since then I insist on OEM cast. Theres NO reason to run a forged piston under most circumstances for the average rider.

Polar,
I had similar issues back in the late 70's with my RMs, but know that they are NOT the problem they used to be with their pistons & have been using them since 89 with good success. I am new to the K5 but every nasty grenaded motor that I have seen had a cast piston (which was neglected) but yet to see a forged piston like that.
You posted you have a shifter kart? I would love to here more about it & what it is like to drive.

the wiseco piston is the best piston i have seen for the kx 500 ,,,,,cast pistons are not on the same level ..
GREENKAW24:
Pro X/Vesrah/OEM rods, Wiseco or even Wossner pistons. Forged is stronger than cast, plain and simple.
