OEM brake pedal is made of relatively soft aluminum. In case of direct impact, pedal bends easily. That is OK, since it prevents it from snapping, but it is easy to put a hole in clutch cover. Picture of OEM pedal bellow.
For my previous KTM 690 Enduro I made aluminum reinforcement plate and I weld it to the OEM lever. More info here. That worked well. I also rounded sharp edges on OEM foot pad, as The Letter J suggested here.
But for new bike, I decided to replace the OEM brake pedal with much stronger aftermarket pedal.
Both are very nice billet units, with similar price. My riding buddy has Rally Raid pedal on his 2008 690 Enduro and he is very happy with it. But I went for Cleanspeed unit, since I really liked their Stepped pedal pad (purchased separatly). Also, I got recommendation for it from few riders I trust and friend from US helped me to get it. Thanks Bill!
I am really impressed with craftsmanship and overall design of Cleanspeed pedal. It is very nicely machined and has two sealed ball bearings "for a smoother action and longer life".
As I mentioned above, I also went for Stepped pedal pad, in orange.
Cleanspeed pedal is much more substantial than OEM pedal.
Installing is relatively easy, but torque wrench is a must, IMO. Footrest hanger must be removed, but it is 5 minute job. Everything is a spot on and fits perfectly.
There is more clearance between clutch cover and brake pedal. Also, Stepped pedal pad looks more gentle than OEM foot pad.
After installation I did short ride, and everything was very smooth. Gros Buck from Advrider installed one in August 2012th and reported everything was still good in September 2015th - reported here. I hope my pedal will serve me that well too.
