2017 CIK/MSA Nose cone rules & Issues

Recommended Posts

So, we have had MK1 and MK2 nose cone blocks and MK1 and MK2 bumper bars.

A total of 4 revisions to get this system correct and it appears there COULD still be issues!

A new rule for 2017 (March onwards) states that there must be at least a 27mm gap between the chrome front bars (Upper and Lower) and the plastic fairing (Nosecone).

It appears from early adopters that an area on OTK chassis, with M6 style bodywork, are very close to the limit. If the nosecone were to move left or right, it would be classed as illegal.

Here is the actual rule:

There must be a clearance at all points between the front bumpers (lower & upper) and the front fairing of a minimum 27mm at all times.

Facebook User, Max Tyler noted that one area of the OTK M6 nosecone is VERY close to the 27mm limit and any sideways movement could cause one side to be under 27mm. We have highlighted the area concerned:

This seems to be an issue on the OTK karts as the bodywork follows the contours of the bars quite closely.

OTK have released new bars (upper and lower) for 2017 to meet the new regulations set out by the CIK. It could be that the new bars have actually introduced this problem and that OTK may now have to release a new M6 nose cone to cure this problem. We will update you on the progress when we find out what's happening!

Will it ever end?!?

Still no confirmation of a "New" M6 front nose cone.

Used nose cones seem to be falling short of the 27mm.

One case of a brand new nose cone with new 2017 bars reported that the gap was larger than 27mm, but this was marginal.

It's not yet clear whether new nose cones are slightly different, or if used nose cones are deforming after contact. It's likely to be the latter as there is nothing being said about a new spec M6 nose cone.

Summary

It seems as though most nose cones are managing to be inside the rules with the new bars. I've drafted up a little summary of which bars you require depending on which Chassis/Bodywork you are running.

2013 or newer OTK chassis with M6 or M4 bodywork:

2012 or older OTK chassis with M6 or M4 bodywork:

All bumpers are listed on this page: http://www.spellfame.co.uk/cgi-bin/sh000099.cgi?REFPAGE=http%3a%2f%2fwww.spellfame.co.uk%2facatalog%2fNose-Cones.html&WD=viper&PN=OTK_.html%23a2614#a2614

If you are having difficulty finding the viper bar, for some reason Spellfame do not list it under the OTK > Bodywork category, only under "OTK spares for Tony Kart > OTK Bumpers Front & Rear".
