Silly shifting question
I took the beginner MSF in the early '90s. At that time, my instructor said that older bikes didn't have good brakes and needed to use engine braking to supplement stopping. He indicated newer bikes didn't have the same issue. (I don't know if this is true or not, but it is what he said). I have anti-lock brakes. The owner's manual and the DVD that came with the bike about ABS, point out that ABS will be no help when using engine braking. So, there is, for me on my bike, a greater risk associated with engine braking than with straight brakes because I take ABS out of the equation if I use engine braking. I take this to mean "times they are a changin'" and the more bikes fitted with ABS, the less it will make sense to use engine braking except in special situations like riding down a mountain.
My guess is that what they are saying is that if you down shift to too low of a gear that the back tire starts to slide, the ABS won't help...well duh.
That's my take on it, but what do I know...disk brakes were a big deal to me
1. Shift wherever you want to, it's your engine
2. Engine braking works but does not contribute to braking if you are also using the rear brakes
3. Constantly downshifting to slow with engine braking causes excessive, unnecessary clutch wear
4. Brakes work better than engine braking (60-0 with engine braking .2 miles = 1056 feet, braking with brakes 60-0 about 140 feet; both distances on good dry pavement)
5. Brake pads are much cheaper to replace than clutch plates (Clutch replacement at dealer $1000+, brake pads in about 30 minutes in driveway $60)
6. Most people do not know how to properly use a manual transmission on a car or motorcycle (i.e. when trying to accelerate as fast as possible, most people upshift at about 3000-4000 rpm causing slower acceleration that running it to redline) (i.e most people ride and drive in too high of a gear for the circumstances; 6th gear at 45 mph)
7. Running your engine to redline will not hurt it. That's what it was designed for.
8. ABS only works then braking with brakes (Antilock-Braking-System)
9. Brake pads on a Toyota Prius can last 150,000 miles or more because it uses an electric motor for regenerative braking (instead of heat, excess energy is converted to electricity and stored in the battery pack) under normal circumstances! Maybe the new electric Harley will make everyone happy!
10. This thread has been entertaining and WTF all at the same time!

what we were taught is to pull in the clutch and hold it in while you use front and rear breaks to stop the bike, but you down **** to keep the gear selection appropriate for the speed your going so if you have to do an emergency speed up you will have the proper gear selected.
now for why not to use the engine to break, because it the rear wheel and we all know the rear wheel is easy to lock up, so any gravel, sand, water, or painted lines that just happen to be there at the point most people will let there clutch out to fast could put the bike into a slide.
lots of people do it, I do once and a while until I am in the 3rd gear range, but also remember that breaks are cheaper than motors.
some one compared big rig engine breaking to bikes, that's just silly, since when did Harley start putting jakes on out motors? our motors don't have a lot of breaking power, but some, and they are definitely not designed to be a breaking system like a big rigs engine is.

"Brad,
I came across this post on the Harley forum I frequent, in a discussion on engine braking. The poster is from Canada.
Is there any validity to his post? Please elaborate!
Thanks, "
His reply in its entirety:
"Certainly not, we teach people to use the gears, clutch and brakes smoothly both up and down through the gears.
Emergency braking; pull in the clutch as you apply both brakes (threshold braking) and snick down through the gears so when you come to a stop you are in first and ready to make an emergency evade if necessary.
Take care my friend, I know we wont likely see you this year, but certainly hope to see you next year J Im probably headed for Sturgis next year for the 75th.
Btw 15 years teaching motorcycles if he asks
"My reply back:
"Thanks, Brad, I was relatively sure he confused regular braking on the road coming to a normal stop, with emergency threshold braking, the same as is taught down here."
Steve, your comments about the "any gravel, sand, water, or painted lines" are covered late in the course under "Special Riding Situations." In that same section other hazards are covered including gravel roads, riding downhill on gravel, rain grooves, bridge gratings, bumps, cracks and potholes, pea rock, mud, snow and ice, spills, load limits, tire blowouts, and broken clutch cable all of which may necessitate braking other than the normal stopping that you would have on a smooth, dry road free of hazards, when you use engine braking in conjuction with your front and rear brakes.
Yesterday, my lady and I rode over to Sioux Falls for the demo rides at the Indian/Victory dealer. There was a long, gradual downhill on I90 coming into SF with a left then right turn at the bottom due to road construction. The speed limit went from 75 to 45 to 15 mph. Because of this thread, I was paying particular attention to the semi in front of us, who went all the way down that hill to the turn without braking until just before the turns, but I could see the puffs of smoke from his stacks as he properly shifted down through his gears. I also did the same thing, and went through the turns in second gear at about 15 mph, all without needing to brake.
And yes, I was keeping an eye on my mirrors and would have flashed my brake lights at traffic behind, had the need arisen.
The dealer ran my bike through his shop for a check over and test ride to establish a trade in value, and the only problem was slight cupping on my front Dunlop, which has over 20,000 miles on it. The brake pads were fine, as was the clutch.

The ABS equipped bike is safer than non ABS. No amount of experience or skill can match what ABS can do.
