Slipper clutch or Full Ti race exhaust?

  1. Stops the rear wheel from locking under down changes. So in theory u can just bang down the gearbox at any speed and let the clutch out with no drama

    So say if you’re trundling along in 3 figures and suddenly slip it down to 2nd for e.g., isn’t that likely to do some internal damage?
     
  5. Red - is that so you can slow yourself down boot the shit out of a car then speed off into the distance haha ;)

    :lol: no but genuinely interested in one


    sounds like a reverse quick shifter (which i adore) but I don’t understand how it works (not that ive ever had a back wheel lock up due to down shifting too quickly)
     
  7. im assuming to down shift you still need to pull the clutch in

    not with a dynojet quickshjfter down shifts are just as easy as upshift without clutch. at least in mine thisnis the case, although im not sure what damage if any could be caused by not engaging clutch
     
  9. I remember on my sv650 I could downshift without using the clutch if you got it right but like you say probably doesn't do it any good lol

    thats what i mean though, no need to get it right on mine she does it every time also without letting off the gas!! its strange ive never none it to happen on any other bike but then again never had quickshifter before
     
  11. But surely the quickshifter does nothing on the down change it only activates in one direction ????

    im not sure whats allowing it to happen i am just asuming it the qs as no bike ive had in the past has done it so easy :s
     
  13. The Triumph 'slip & Assist' clutch improves lever effort, can cope with more torque (I believe) and doesn't lock/unsettle the bike if you are lazy and can't be arsed to match engine speed when downshifting.

    As people have previously said a good rider that blips the throttle on downshifts won't notice the difference of the slipper clutch.

    I like mine as it saves me thinking about blipping on downshifts into corners on track, oh and the fact I have the grip strength of a 12yr old girl so the light clutch lever action is a massive plus.
     
  14. When you say blip the throttle again my ignorance. What does that mean
     
  15. Reving the bike when the clutch is in, this brings the engine speed to the same speed as the wheel is going.

    The ideal being that as you the release the clutch the engine is at the correct speed (match with the rear wheel) so you avoid unsettling the bike or worse locking the rear wheel as the engine try's to slow the rear wheel.

    Whilst it may be a worthwhile skill to retain as StM says, if you're looking to improve lap times then anything that frees up a little bit more of your concentration quota is a good thing. Have a read of Keith Code, it actually makes good sense and works, (for me anyway).

    I'm liking the sound of this new innovation from Triumph and would consider fitting one of these next year if one came along at the right price. I'd want to ride a bike with one fitted first though....
     
  17. I like Keith Code's concept on concentration being a finite amount and not having to worry about downshifting to early and locking the rear does help (IMO) on track.

    The biggest different is clutch effort, I used to have an STM slipper (beautiful peace of kit) and have ridden a lot with the std pre '13 clutch both of which are quite a handful and after a few laps my girly hand will start to cramp.

    If we are at the same trackday next year we can swap to give it a try for a session, std rules apply - you bin it you win it!
