Racing Classes

[MaxCannon]

Apolgies if this has been asked before - tried a search.
Can anyone explain what the different racing classes in NZ are ?

I see terms like Superbikes, F1, F2, Supersports, F3, Protwins, Streetstock

How is the eligability defined - capacity, horsepower ?

I assume some classes are run together and some classes may be club specific but each time I browse the racing section I get more confused.

I'll getting a track bike (as soon as a sell a house) and ultimately may want to dabble in a bit of racing.
I know beginers go into clubmans which seems to be open entry.

Go to appendix A / B / C / D and have a read bro !
F2 is a fun class as ya can run in F1 as well (my personal opinion) others say post classics is cool cause there is always someone to race and ya can cross enter into F3 or F2

Awww to hell with it just drill a hole in ya sump plug and come to the track with a back protector and i'll explain all there !

The only real stipulation with Clubmans is you can't be faster than a certain level.

All other classes are sorted effectively by engine size. For a full run down of the rules for each class you need an MNZ book but basically as follows.

Production Superbike: 750-1000cc (Could be open actually) Production based Sportsbikes with fairly limited modifications allowed.

F1: Similar in engine capacity, except the rules are a lot looser and also caters to race bred machines. Most clubs run F1 rules withing their own championships, as do the street meetings. Effectively, there's nothing to stop you racing a MotoGP bike in this class.

600 Sports Production: Road based up to 600, limited again in allowable modifications.

F2: Up to 600cc four cylinder 4 stroke road based machines, 750cc V-twin 4 strokes, 250cc GP machines.

F3: 650cc twin cylinder with limited engine modifications, 450cc four cylinder 4 strokes and 250cc 2 stroke road based bikes. Technically, motards also fit within this class however some clubs will banish them to their own class.

Pro-Twins: 650cc road based twin cylinders with VERY limited modifications allowed.

Would be good to have this as a sticky with a rough breakdown of the mods that are and aren't allowed. Basically a kinda of laymans guide.

Best to keep it simple and to displacement, anyone interested should keep an eye on the MNZ website rules as they're always changing.

And particularly for Sinfull and Wharfy, APPARENTLY you are allowed 675 triple cylinder machines in F2 and Sports Production.

In addition, to MNZ rules each club can set there own rules around entries into classes, and these are explained in the races supplementary regulations. The MNZ rules are used as guidelines and extrapolated out.

Ahh ok. Sounds like a bit of a minefield for newbies. When I get into racing I guess I should just buy a second hand protwin or F3 bike so I know it's going to meet the regs.

You all forgot to mention 125cc GP the closest racing class in NZ. I also think the cheapest (2 wheels - national level)
Who saw the TT race on the tele last week, I lost count of the amount of lead changes in the race. I think there was more passing in that televised 125 racing from Puke than the SBK class saw all season (at the pointy end)

Of course I am biased.
