Thanks Stevie.

I've been looking at the bars online and I think the 22mm Renthals in Black will do me fine.

Good point about the drilling the hole - thanks.

Quick question about the Hardguards though:
How in the hell do I remove the gubbins from inside the original handlebars! I can remove everything else from the bars but the gear inside that the end weights or handguards bolt to will not shift.

Slidding hammer anybody?

P.S. Stevie, you got a set of straight bars there? The look a lot shallower than the originals. I was thinking of going for some with more height on the grips as I use the bike offroad at weekends and like to do my riding standing up (Oh err missus!)
