Wrong! He has to go to North Pole...

 

LOL... nope. the coriolis effect changes at the equator.

 

Try to install pink grips, it should stop pulling!

 

Another consideration could be you. Don't take that comment the wrong way, because I'm crooked now too. My bike drifts left with balanced saddle bags, et al., but my lower back and hips are misaligned, so my "natural" riding position has my body leaning left. I can compensate for it, but it's quite uncomfortable...Just another perspective.

 

Bringing up your mommy may often be your first instinct but do you think your sense of your own maturity may be over-rated? Big boy?

For those who were baffled by my simple comment: "Keep your hands on the bars. End of problem", the OP has had no trouble with the bike's handling until he let go of the bars.

Guy walks into the doctor's office, raises his arm over his head, says: "Doc, it hurts when I go like that." Doc says: "Don't go like that. That'll be $100."

 

Coriolis effect:You ride North or South, bike will pull West.
There is no coriolis effect if you ride East or West.
Nothing changes if you cross equator.

 

All bikes may drift a little left/right, but it is definately not normal if it drifts enough that you think it will go over. I would look for uneven tire wear, but I think the best advice is to have someone check the alignment. It could be many things, but out of alignment would be the most obvious.

P.S.
I regularly take my hands off the bars just for the purpose of troubleshooting problems; looking for drift and wobble. What's the friggin problem with that? Ignoring a suspected problem can at the least cost you money and at the worst your life. Taking your hands off the bars for short distances on straight even surfaces free of traffic should be safe enough as long as the bike is in good working order. If it isn't... well that was the point.

 

Not gyroscopic progression when the bike is in a steady state, although when the handlebars are turned left or right it will have some effect, helping the bike to lean over.

 

your rear wheel probably has a slight offset from factory, this is common,especialy since yours is a 200 rear model! that could be the cause and nothing to worry about??? just an idea

 

Um not quite.....Coriolis effect does in fact change at the equator. Might want to google it. Basic spherical geometry and one of Newton's laws of motion.

I have no idea what you are referring to with your example. Sounds like lead/lag times of a magnetic compass.

My guess is the rear wheel is staggered on the shaft. The left side is farther back than the right. This happens when trying to tighten the belt. But this is just a guess and YMMV.....

Good night
