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 stock some extended pegs for DRZs and T7s on my sell page but Lee can sort you out for all other pegs. His prices start at $80.00. He can also custom make you something very different if you want it. Contact him on email@example.com to work out the details and a drop off.
