We have just purchased a R31X, to go along with the AR1 my Son races inHonda 4 cycle. What class is the R31X best suited for? Would it make a capable kart for Rotax JR?

It depends on the size of the Jr. Rotax driver. WE have just completed testing with a very small driver. Last year he did well with an AR28.. this weekend and the track was changing by the hour, he did well with a AM29...That is a blend of 28 and 30 mm tubing. For me a Jr. Rotax might not do as well with theR31. The problem with this weekends test, the dad did not go back to retest the AR28 which sent his son to the World finals in 2004. AR 28 has been our very best peforming Jr.Rotax kart and I think it still is the best. But once again it all depends on the size of the driver.

Our driver is approx 5' 5" at 120 lbs. Just gonna test the waters this season and make the full asualt next year. Was this chassis designed for ICA/JICA?
How can I tell the year? Thanks

The x on the end of the R31 says it was 2000 or 2001, but that doesn't mean it was put into service at that time, it only represents the manufacturing sequence. For example a chassis like that might have sat in a show room for a number of years before getting out the door to an end user.

The current designator is T for 2005 production models.

Hi Garry, Do you mind me asking what the Z in the R32Z I was previuously asking about indicates...? Is the Z representing a particular year of manufacturing?

X was 2000 or 2001 and then came Z followed by SR and then the next year SP and ST for the current year.(2005).

As stated before that was the manufacturing of the kart, yet karts might still be considered new sitting in the show room For example I have a few Q31Z karts left that are new.
