Hi all,
Please tell me the weight limit for ROK in ya country....
1) For an ROK senior race
2) For an Open 125/TAG senior race

We're having 160kg limit for ROK engines users in an Open 125 race here in HK, the Max are 165kg in the same race, I think it might be too heavy for the ROK engines user.

Thanks!

When we had ROK (with Rotax allowed to race as well) - ROK Senior was at 165 and Rotax at 165 or 170. Mid-season though the organisers changed the ROK weight to 160 because Rotax had too big an advantage. I think since then the International ROK rules have also been changed to the 160kg weight from 165kg. I think some countries have still stuck to the 165kg weight for ROK Senior though because driver weight has to be quite low to meet 160kg.

Oh yeah for most tracks I'd say close to a 10kg differential brings the ROK senior to about an even playing field with the Max. At other tracks 5kg might be enough.

But in AKOC, the open 125 weight for ROK is 155kg and Max is 165?!
Still when the 2 engines raced together (like AKOC @ Thailand), the ROKs were back behind, half a second slower than the Maxs each lap.
