HOT RODS CK111, what size is it

[wes350x]

Ive tried searching on the new and I havent came up with much, I got a Pilot Cylindered 250r from ftz and I found this rod in it. FTZ told me it was a 4mm stroker that is used in it. The whole bottom end was rebuilt last year so Im just trying to piece the puzzle together. It says CK 111 HOT ROD.

It is a KTM 250-300 rod. It is a stronger rod than the stock long rod. It is a 132mm rod while the stock long rod is 130.3mm

Thanks! So its a 2mm stroker? right. I spoke to Dennis at FTZ and he said he built them with +4mm.

you get 2mm on up stroke and 2mm on the down stroke
='s 4mm

The rod doesn't change the stroke of the crank. It changes where the piston travels in the cylinder. You still could have a 4mm stroker crank with a 2mm longer rod with a shorter pin height piston. You can measure the stroke using a digital dial indicator.
