Rear Wheel Lock-up

Is it my imagination or is it REALLY easy to lock up the rear wheel on the non ABS model?

Yes it is. I did it 3 years ago, must have had my R a month.sloopy_farklehump wrote:Is it my imagination or is it REALLY easy to lock up the rear wheel on the non ABS model?
Haha I asked the same question on this board on the old site about 5 years ago when I first bought my 2002. The funny thing is that most people didn't seem to think so and told me to eat more pies to gain weight.sloopy_farklehump wrote:Is it my imagination or is it REALLY easy to lock up the rear wheel on the non ABS model?
When you can lift the rear wheel using only the front brake, what does rear braking add? It should be relabeled as a "hillholder" as that is its best function. Concentration spent trying to modulate the rear brake without lock-up during an emergency would be better spent on other cognitive activities more important at the moment. The problem with relying on rear brake use in normal situations is that you will fall back on that in an emergency and stomp hell out of it (then fall down and tell everyone you "had to lay 'er down"). ABS exists (and makes sense) for this reason, and if BMW's wasn't technically absurd I'd have it. They should copy Yamaha or Honda.Oilhead wrote:<snip>...However the truth remains that the bike will always stop quicker with the proper use of the front and rear brakes.
My R came with SS lines, didn't yours? - LeeI will be doing my rear pads soon. I will be replacing my hoses with a Spiegler SS hoses to improve the feel.

2002 R1150R(& I believe the 2003 also) sold in the US did not have SS lines as it was not approved by DOT at the time.beemerphile wrote: My R came with SS lines, didn't yours? - Lee
I don't know if you have read Keith Code's books, but they changed my views considerably regarding rear brake use. I tend towards hyperbole and shouldn't have been so absolute. I also use rear brake on slippery surfaces because maximum braking is not available. However, I have trained myself out of rear brake use for most other situations in order to train out the instinct to use it in an emergency.Oilhead wrote:If you are advocating that one should completely ignore the rear brakes, that is a terrible terrible advice. If one does not know how to use their rear brakes, you will be in a whole load of sh!t if you encounter any kind of a slick surface. One should be totally familiar with the full potential of both brakes and use it accordingly to the situation.
Yes. from about 40 years ago when I was essentially ignorant in the sport.As for your story about stomping the rear and laying it down, is this something from your own personal experience?
No argument with your statement, but I expect that my definition of "proper use" of the rear brake is significantly more limited than yours.Once again, it goes back to my original statement of "proper use of the front/rear brakes" & "practice practice practice".
As a 1970's motocrosser, we're going to agree on that as well.I think all street riders should ride in the dirt, it is amazing how much you can learn riding in mud, sand, & gravel. The learning experience is priceless and may save your hide one day.
Are you talking about Twist of the Wrist series? If so yeah I have those books. From what I remember, Code says not to use the rear brakes on the track correct?beemerphile wrote: I don't know if you have read Keith Code's books, but they changed my views considerably regarding rear brake use.

I certainly respect a man who is honest.beemerphile wrote:Yes. from about 40 years ago when I was essentially ignorant in the sport.
So ironically, we basically agree on just about everything!beemerphile wrote: As a 1970's motocrosser, we're going to agree on that as well.

Yes, Twist of the Wrist 1 & 2. He talks about your $10 worth of concentration and how you can only spend it once. The $2 or so of concentration that you spend trying to modulate an ineffective rear brake is better spent plotting an exit or even a dismount strategy. The rear brake is minimally effective in hard braking on good traction surfaces because the weight transfer is so heavy to the front end. Maybe you are not to the point of a stoppie (my hyperbole strikes again), but there is not enough weight left on the rear to make it help much in scrubbing off speed. It is easy enough to skid the back tire on a good day (which is what started this thread!), but under maximum braking on good pavement with a Buick in your face, it is almost guaranteed. Because it doesn't help much and it occupies a lot of concentration, it is a bad expenditure of the mental resources in an emergency. The way to assure that what you do in an emergency is technically correct rather than an inappropriate survival response, is to make the technique your standard practice. Look, this guy trained Wayne Rainey. As far as whether track tactics are directly transferrable to the street, I think they largely are. If you are racing at 10/10ths pace and somebody blows it in front of you, the same tense time-bound emergency exists as when a dumb cager makes an unannounced bid for your space. In such a case roadracing skills can save you. And in such a case, I don't think Code would be messing with the rear brake.Oilhead wrote:Are you talking about Twist of the Wrist series?

I think we mostly do. It is just in the definition of "proper". I use the rear brake under specific limited conditions, but I have otherwise trained myself off of it for normal and emergency braking so that I do not instinctively apply it at a time when it would not serve me well. I do not assume that I have $20 worth of concentration available when I only have $10. Hell, at my age I probably only have about $5.25 left. If I have to pick something to ignore in an emergency situation in order to process the remaining data correctly, the rear brake seems to me like a good thing to forget about.So ironically, we basically agree on just about everything!
