Most standard foot pegs are simply not wide enough to be a comfortable platform for standing for long periods. Wider pegs improve your balance and reduce your fatigue. Lee Greer will sort you out and extend them by around 20 mm which makes then just the right size. Extending your own pegs is far less expensive than purchasing after market pegs.
I have Lee Greer DRZ and T7 extended pegs ready to go on an exchange basis for $85.00. Lee's prices start at $80.00. He can also custom make you something very different if you want it. Contact him on firstname.lastname@example.org to work out the details and a drop off.
