Hey everyone, since the next call looks very focused on rules, David Cox and I put together some data on the rules being run nationwide. We looked at 118 different LO206 classes (every one we could find data on) to come up with some recommended rule sets for maximum commonality: http://kartrank.com/lo206-data

There is a lot of data there so I’ll copy the short version here:

Briggs LO206 Masters
There are not enough Masters classes (only 5 nationwide) to make a recommendation. Of the classes that exist the rules were in line with LO206 Senior (except age), so there does not seem to be a compelling reason to offer a Masters class separate from Senior.

As a service to everyone looking to race LO206, David Cox and I put together this interactive map with all the tracks in the US that offered the LO206 package in 2014. We’re LO206 enthusiasts ourselves so we thought this would help others out too. This was all taken from track websites that posted their class offerings information.

We’re working on a spreadsheet comparing all the LO206 rules variations across the country to help all the tracks and series looking at rules for 2015 (hopefully more commonality!)

Steve if you could share the tracks/series that have contacted you that would help us get it as accurate as possible. team@kartrank.com will go to David and I.

(Note: not trying to compete with the Racingwhere.com plan…just had the track info and this was the best way to get it out there)

First, I don’t intend this as self-promotion. Over at KartRank.com we have data on kart counts for pretty much every track in the Eastern US, and for Midwest tracks we have data going back to 2011. If anyone would like some specific data I’d be happy to provide it.

In general my take is: Cadet Sportsman is dead (really just a Man Cup class), Komet classes of all varieties are basically dead, Yamaha is just kind of maintaining. Clone seems to have turned a definite corner and is on the way down, with almost every track except some in the SE switching to 206 or running a combined class. 206 is really exploding this year.  At the national level Pro Gas seems to be the only game in town for 4 strokes, not sure why Gold Cup even bothers with the rest. Events like RIGP have very strong 206 counts, so I think it can work for big races.

TaG is fracturing, seems like every manufacturer wants to be like Rotax and have their own series, with lots of Leopord/Parilla only and now Rok Cup.  I’m guessing this can’t be good long term.

Canada might have the right idea with the Rotax/206 combo.
