Looked for this myself but there were non to be found, on ebay there are many counterfiet BMW reprom dvd's being sold but they are old. So i ordered the dvd off of bmw, about 100 dollar but man is it sweet, online updatable so i will have all the latest news when it comes to diong maintanence and trouble shooting. This is the same info that the dealers work from, pictures and also all the special tools are covered and all parts have their partnumber shown. All torque and specifications are there.
Just perfect for us that want to maintain our own bikes. The dvd covers all K4x series bikes, both US and european setups.
