Haven't ordered from TYGA in a while but everthing I did order was not predrilled and required drilling by me, but its no big deal to do it yourself, in fact I think its better this way as all bikes measure up a bit different. Not a big deal to drill em out, TYGA parts are built quite heavily and no worries of cracking...make sure you drill the bodywork and fit it before you paint.
Cheers,
Jamie
