School me on what classes the R3 can race

I just picked up an R3 and looking to race it next season. Assuming it is Lightweight SS? Is there a SBK class also?

Am I going to be racing against Kawi 400cc? Sorry I havent paid attention to the other classes as I just raced the R1 in 2018.

 

At a regional event, classes are ESS, can bump up to DSS, DSB, and Clubman. Can't run all four as one of the D classes runs with Clubman, DSB I think. At a national event you can run 300SS.

Those are the normal ones. Sean may allow some faster folks to bump into the light weight twins classes, but if that happens I haven't paid enough attention to notice it.

 

I appreciate it. Looks like Clubman and and D. There isnt alot of guys at Wera West racing these classes in 2018. Hopefully we get some bigger grids in 2019 to make it fun.
