1978 BMW R100S Restoration

A 1978 BMW R100s fixed up and released back into the wild.

This bike is an absolute dream to ride. It runs amazingly smooth.

I had to go through some serious DMV hoops to get the salvaged title status back on the road with a deadline of 5 months until I incurred DMV penalty fees.  I made it to the registration day with 2 days to spare.

I cleaned, restored, replaced, rebuilt whatever it needed to get it back on the road.  The front end is from a spare R90/6 that I had lying around.

This is one of those things I try to do to every BMW motorcycle I rebuild.

The Motorcycles Cushman Truckster is one of the more popular models of bikes in the United States. It has been around since the mid nineteen-hundreds and has always been a top seller among collectors and bike lovers. While it doesn’t come with a warranty, you can get around that by getting a Cushman Tribute package, which pays for repairs or parts that might need them in the future. There are many sources online for Cushman bikes, including parts selection, prices, and even complete restoration packages for your bike if you’re not sure what you want to do with it. When you buy this bike, be prepared to spend a little extra money up front to purchase the bike you want. But remember, it will end up being cheaper in the long run because of the extra care you’ll be taking with it.

It is almost never the engines in BMW`s that are the problem; properly serviced with clean oil at regular intervals, and no abusive riding, they should easily see 200,000 miles

This area is cracked on nearly every frame I tear down. It is the rear foot brake area which also is the muffler / silencer hanger, and where the passenger foot pegs attach. This frame is a 1978 BMW R100s. If you are considering rear sets on your bike that attach to this section, then I HIGHLY RECOMMEND doing this procedure.

New piece of metal to weld onto the old cracked section to reinforce the area making it MUCH stronger and no longer prone to cracking.

This bike is a blast to ride. Fast and zippy for a small bike but next to a real motorcycle, you realize how slow you are going! The restoration took about a year. I had help rebuilding the engine and transmission. A friend Adam helped me weld the bump onto the seat. Chrome, powder coat and paint were all locally sourced. Custom YSS shocks. Assembled by me. The only bummer is that I could not find the correct street Bridgestone tires to put on the bike.

I sourced this engine build to a guy who builds Yamaha RD's and such.  Fingers crossed it works.

Painter went all out... all i needed was the rear dome painted.  I'm not complaining.  It looks amazing. The tank looks killer.  Photos of that to come
