You don't need one. From 05 onwards the S3 comes with a "back torque limiter" which does a good enough job on slipping the gears on downshifts. It is pretty much impossible to get the rear to lock and there is much less engine braking than on earlier models.

If you are doing hardcore racing and have come to the conclusion that you need one, then please disregard the above.

Ahhhhhh, my mind is at ease.

A back torque limiter is essentially a slipper clutch. It was one of my few concerns as I love to drop 2 gears when riding aggressively, and that seems to be a problem on bikes without them.

With them, it is a dream ride.

I have not ridden anything with a slipper clutch, so I have nothing to go by. All I know is while braking hard, and unable to blip the throttle I have felt the back tire get pretty squirrelly on me during an aggresive downshift. I would not want to be leaned over when this happens.

Is the back torque limiter supposed to disengage completely on downshifts, or is this normal.

Clueless

In lower gears, particularly going to 1st, my back breaks loose too.

A back-torque limiter is indeed a slipper clutch; different words.
And no, I don't think the S3 has one gentlemen; it'd certainly say in the specifications, and probably in bold letters; it's an expensive upgrade. Only a handful of hard-core sportbikes have one.

Edit
After doing a little research I was unable to confirm the following. However, I do remember reading that the new 1050 Speed Triple had a "Back Torque Limiter back when the model was announced. I think this was a mistake based on the fact that the bike unequivocally does have a Clutch Backlash Eliminator Gear- not the same thing at all.

None of my saved articles, brochures, or current web sites mention a slipper clutch or a Back Torque Limiter. But I'm leaving the following posted because it's essentially correct, other than it's wrong about the S3. :razz: :razz:


The 05/06 Speed Triples certainly do have what they call a "Back torque limiter" that is essentially a slipper clutch. One of the first mainstream bikes to have one. This was in all the S3 press releases and early magazine articles. However, it is not mentioned on the Triumph web site. It wasn't one of the main selling features.


The confusion here is a misconception of what it does and how it is constructed. The key word is "Limiter." This device limits back torque on down shifts, which makes it more difficult to slide the rear tire on downshifts. With a bike like the S3 that has tons of torque you need this.

Basically the way it works is on the back of the clutch basket is a ratchet device that allows the clutch to positively engage the teeth when the torque is in the normal direction, but when there is back torque the teeth slide against each other under pressure from a spring. The effect is like a secondary clutch that only works under reverse spin. If your back tire has less grip than the back torque limiter then it will slide, if the limiter has less grip it will slip. The limiter will never allow your clutch basket to free spin under these circumstances, as this would be dangerous.

However, this doesn't stop you from being foolish. If you downshift from 4th to 1st at 60 mph you are going to slide the tire, no question. The back torque limiter can't handle this amount of abuse.


I hope this clears things up.
