First "Solo" Ride on a TU250...

So would you say during a 30 minute commute, 15 minutes just under or slightly above 5000 RPM is ok? I'm convinced a motorcycle engine much more "delicate" than a car for some reason. When I bought my truck, I was "gentile" with it but I did drive at highway speeds with out thinking twice. I guess I should do the same with the bike.

There are also varying theories about break-in periods.

I always ride the bike the way I would normally ride, from scratch. I mean, if those rings and heads aren't broken in within 100 miles, I don't see how they ever would be... but that's just me.

You can read up more on break-in theories just by google searching. Manufacturers have to cover their bases so they slap a generic sticker on ever single bike they produce.

Congrats on your first ride, BTW.

I went with the recommended break in procedure from Suzuki. I have a theory that the various parts must mate properly over a period of time without high stress loads and high RPM. The 5000 RPM thing does seem to be a generic number as suggested and it worked for me. Some folks just ride em like they stole em and it works for them. Choices, choices and more choices. Pick one and be happy.

I don't know about the Geezer, but some cars used to have "break-in" oil and some mechanics used to claim there was more metal/junk in the first 100 miles or so, that would be taken out with an early oil change. Could have been marketing bullshit for all I know. I rode mine (GZ) at the speed I was comfortable with, which was certainly more than 50 mph after the first 100 or so miles. I still haven't reached 5000 on my Geezer (at about 4750), but I'm closing in on 15K on the Strat. I didn't go slow on the Strat at all (not really feasible out here - you got to go at least 70 unless you want to be the cause of a chain reaction pile-up. I usually go 75-80 depending on the speed of the other traffic. I try to make sure there's at least one dude going faster than me so he gets the ticket [theoretically.])

[geezer]

dude running at different speeds and different rpm is what you need to do to avoid the cyinderwalls from glazing over. im sure it says right there on the bike somewhere no to do a constant speed (RPM) for to long, and this is the reason. just ride it man, just ride it

After changing the oil early on in several new vehicles, I can at least attest to the metal shavings part being accurate. All engines have some machining/honing scraps left in there that have to be flushed out with use. From lawnmowers to Mercedes. It's just part of the process. Filters will catch most of it. Early oil drains should remove the rest.
