My driving instructor explained to me, that when usign the rear brake (also at speeds where you rely 99% on your front brake) it functions like dragging an anchor behind a ship, helping the bike stay on its course.

I think this anchor effect, also means you will not dive into the front suspention as much, as when you use front brakes only. (thus maintaining more steering controll)
Especially with ADV bikes, with their longer/deeper front wheel suspention dive, this would be a more relevent factor.

If also using your rear brake at higher speeds, did not have an important funtion, then it would be very irrisponsible of (for instance) Yamaha to introduce UBS and they would not have done it. (concidering liability claims etc.)
Right?

On the street, that braking "dive" can be very useful. It changes the chassis geometry of the bike and allows the bike to steer more quickly and more precise. On the Tenere, I find braking hard and trail braking to really improve how quickly I can negotiate corners since the factory geometry is very lax for off pavement confidence.

I try not to determine what the "engineers" at a manufacture were thinking when they designed something. Generally the marketing and law departments do more work to develop a product than the engineers.

I originally thought I would hate the UBS. But, just like the ABS, other than the fact that I have just about smoked my rear brake rotor in 20k miles I can barely tell it is working on the pavement.

Off the pavement, I have never ridden a bike that feels so comfortable using the front brake lever.

Sounds like the ABS sensor was either not installed properly, damaged, or not installed at all after removing and installing the front wheel. Did you use a magnetic screwdriver while removing/installing the sensor?

First, tell us some background info.
Where are you located?
How old is the bike? (miles/time)
Did you buy it new?
Warranty?


Problems are often related to the last work done. Did you change the pads, or did you have it done? If you had it done, buy whom? (dealer or??)

It's far more likely that the ABS sensor is bad or not giving a correct signal than the brake is bad. The speedo shouldn't be related to the sensor, getting it's input from the VSS sensor at the trans.

Was this a wrecked/salvage bike?

Did everything work before the last work done?

So this problem showed up immediately after changing the brake pads?

Question

Since my romp in the mud yesterday, my check engine light has been on. I hosed the bike down and thought it would clear over night but it hasn't. I removed and cleaned both abs sensors but I am still getting an error code 42. Any advice?

im located in Singapore.
its been a year and half around 20000km.
yup bought it brand new.
warrenty only 1 year, im 6 months over.

yup the pad i did it on my own by just removing both the caliper clear the brake dust and putting in the new pad before fixing the caliper back.

sorry still not to technically into the electronic stuff im not sure what is the VSS sensor.

nope the bike was not wrecked.

yup everything was working well eventually after i did my brake pad due to hearing some scraping sound from the front brake.

i did brought it back to the dealer and they also have no clue about what went wrong BUT they suspected is abs pump is at fault and they could not give me an assurance that after they change the abs pump it will be ok. they quote me a ridiculous price so i did not proceed with the job they suggest.

Per the shop manual it's one of three things-

1) Rear wheel sensor: no normal signals are received from rear wheel sensor.
2) Neutral switch: open or short circuit is detected.
3) Clutch switch: open or short circuit is detected.

Sluggish out of 1st

Many wise men say the ECU flash from AF-1 is the cat's meow.

I expressed my desire to use AF-1 when I bought my Tenere last week and the shop owner suggested I go with the Power Commander V instead.

Not seeing sunshine and roses as I try to get out of first gear on these WV tilted roads. Need a fix so I can stop stalling the bike and flying off as if I were a member of Cirque du Soleil--a dramatic mix of circus arts and street entertainment.

What say you?

Thanks Anti. I do have the clutch switch mod in, so maybe I need to pull it and see if it clears. I've already pulled and cleaned the rear wheel sensor. The neutral light is working properly, so my guess is that isn't the problem. Thanks, I'll let you know what I find.
