Timbersled says to use 14.313" center to center length on the KTM 525 EXC, but all others are 14.188" Why would the 525 be different? I thought the chassis was identical to the 450 EXC. I called and was told to use the longer length, but couldn't get a good reason why.
Also running the 137" length with the 2.3" lug track.
