3cm might be pushing the extremes of your standard cables, I know that as the streetfighter bars are not as wide they give a bit more play in the clutch which is normally the tightest cable, but 3cm higher could be the limit.

Keep us posted with your findings and piccies are a must

That could be a problem. My first choice was rc high, but I am afraid too, that cables will be short and decided to go for rc with hope that they will fit well...enough :eusa_whistle:
For now I am trying to sort somehow problem with shipping from www.bandcexpress.co.uk to Macedonia, we are not on their list. Wish me luck and I will post pictures... and dimension of oem handlebar.

Hi,

width - 770mm, height - 112mm, sweep - 74mm (or should be).

Renthal rc has been fitted without problem. It is better than oem, but renthal rc high is right choice for me (I am 177cm). Next time, if I have chance.
PS
And streetfighter is 1mm higher than rc, but shorter and with more sweep.

Ive ran renthals bars fur years,, an dont come off road based bikes muchl, but i do run renthals in my trials bikes and am forever comming off, an renthals to me oin the trials world are soft an bend ever so easy,, so think again, everyone an their granny has renthals... cheers

I just ordered the 722 Renthal bars after mine bent when the bike dumped in the bush today. The OEM bars must be crap, because they bent hella easy. I thought about going with the Twinwall bars, but I didn't know if they'd work with my bar ends and triple clamp. I ordered the Renthal bars from B&C Express, $80 shipped to Australia, not that bad I reckon.

I hope I don't have any cable length issues with these bars. The 722 is the bar that B&C recommended when you enter your bike details as well. So I reckon these will work fine.
