Renthal Fatbar RC high

[28gasser250]

Hi,

Went out on my mates bike the other day & he's running some renthal fatbar RC bars, they gave a totally different feel to how the bike rides & I fancy trying a set on my bike. I have a 2006 ec250

Does anyone know if these will fit straight on or will i need bigger clamps? It says I need to have a 1 1/8 clamp so I guess the question is what size are the standard bars?

Thanks
