The KTM's of that era (2005 ++) shared some parts in common with the Huskies including Brembo brake components and Magura clutch components. For example my clutch master cylinder went through piston kits regularly until the lining of the cylinder bore was shot. Instead of buying a Husky replacement master cylinder, I bought a Magura master cylinder from KTM for a 950 Super Enduro, the exact item as that on the 630 except it was black, not silver and also the quality was better. That was 4 years ago and no fluid leaks.
