I pick up my new GT next Thursday. I was wondering if any of you are doing anything special to break in the engine?

Keep RPM below 5000 for the first 600 Miles /1000 KM. Then below 7000 till 1500 miles. After that have fun. ;)

By the book:

While running in the motorcycle, vary the throttle opening and engine-speed range frequently;
avoid driving for long periods at a constant speed.

Try to do most of your riding during this initial period on twisting, fairly hilly roads, avoiding
highways if possible.

Observe the engine run-in speeds.
  • <5000 min-1 (Odometer reading 0...186 miles (0...300 km))
  • <6000 min-1 (Odometer reading 186...621 miles (300...1000 km))
  • no full throttle (Odometer reading 0...621 miles (0...1000 km))

I keep to these guidelines.

I have not been easy on it from day 1, lots of throttle modulation up and down the power band and I have yet to see any oil being used or any problems. Ive done this with all my BMW bikes with great success. :)

I am with you on this method. What are you thinking about oil type, synthetic or conventional oil? My first oil change was done by my selling dealer, they used ****** synthetic 5-40. Since the engine used about a half liter over 7000 KM I decided to change to BMW oil which is 10-50 conventional. Castrol has a synthetic 10-50 that I also considered. Not sure on this one but I like to stick to one oil type, and it should be readily available.??? :bmw:

OK, I read that. If the assertion is that the engine is quickly 80% broken in after 20 miles of hard riding, then why isn't it mostly broken in after it's tested at the BMW factory before it leaves and why is this something we have to think about at all?

It makes sense to me that you can make some difference in your engine by how you break it in riding it. I've yet to see anything that suggests that the difference it makes is significant over the life of the engine - other than some photos of nasty looking vs. pristine looking pistons.

Question: can a BMW tech use their diagnostic access to the bike to actually tell how it was broken in? (peak RPM, throttle opening, speeds, etc)...

I agree this is something that always seems to come up in conversation re a new motor vehicle. Many years ago I used to follow "the book" on every new vehicle engine break in. In my first career I worked as a state trooper and we were issued new vehicles roughly every three years. When I rode motors we averaged new bikes every five years give or take. We would leave fleet operations with a brand new vehicle and were on the job. In other words there was NO break in on the vehicles. We drove the vehicle the same way new or old and it was primarily interstate patrol. So much for up and down on throttle and not running at the same speed. In 25 years I never had a problem with an engine in any of my issued vehicles. Yeah I could just hear the radio traffic now...."eh Sarge I would really like to stop this clown that came flying past me at 105 miles per hour but I'm in my my new cruiser engine break in period so I'm gonna have to let him go 'cause I don't wanna blow up my engine..." The next radio traffic would be from the Sarge telling me to see him at headquarters for a tune up! Take it easy for 50 miles or so and then run it!

When I bought my 05 LT, I bought 5 qts. of oil and an oil filter. Drove the 80 miles back to the house using the whole power band, every gear right to the limiter and back again, the whole way home. Pulled into the garage and changed the oil. Have not had a problem with engine in almost 80,000 miles. Chuck

Ditto, that's how I would do it
