The front wheel has one length spokes as does the rear. Last year when I refurbished the wheels on my KTM SMC I sent a sample spoke to Buchanans and they copied them. The front was a single length but the rear has two different lengths. My buddies Honda XL600 has three different length spokes for the rear wheel.
