Ok, I think I might be the only here who........ Doesn't blip! I just have my own riding style, suits me, no probs at all. After reading all this I might have to give it a go to see what I'm missing out on  :biggrin:


Hmmmmm.

On a side note: I just watched the Moto2 race from COTA.  They talk about how Sam Lowes (spoiler - winner) DOESN'T blip the throttle at the end of the back straight.  In slow motion at 175 mph he jams it down the last three gears into 1st, then releases the clutch, like they used to do in the 2 stroke era.

As these bikes have no traction control and minimal engine electronics, I'm guessing the only thing keeping that bike upright is the slipper clutch - or whatever alien technology Honda installed in the engines.

Amazing to watch if you haven't seen it yet.

I don't suppose anyone has tried that one yet?    (popcorn)

That's what a slipper clutch was invented for.

You don't have to blip the throttle with a slipper.  Not sure that technology was available in the 2 stroke era.

Non racer bikes need to match the revs with the speed, thus the need to blip the throttle.

So if the clutch takes care of all that, is it just a matter of rider preference when racing?  As he seems to be the only one doing it, what advantage could it give him?  Or is he just a maniac?

Using the right combo of smooth downshifts and brakes (with a 90/10 emphasis on front brakes over rear) is the smoothest fastest deceleration possible. Just like careful application of the rear brake can help settle suspension, so much so that racers sometimes drag the rear brake to settle the bike into a corner. The inclusion of engine braking (via smooth downshifts - or just being at the right rpm for the corner with the clutch out) also keeps the bike settled and planted under deceleration.  This is particularly useful approaching corner entry and is sometimes a superior technique to dragging the rear.  Trail braking, engine braking and dragging the rear brake are all about preventing the rear from skittering around approaching corner entry and into the corner itself...

Blipping the throttle to keep the downshift smooth plays directly into the need and desire to keep the suspension settled under heavy deceleration....

Ahh yes. that other bible I have yet to read...   :sorry:

I was aware of those techniques individually, but when you put it into the context of combining them it makes it even more remarkable.  I'm into my 30th yr of riding - I just realized that! Holy Crap!  :shok:  - and I've never had the opportunity of track days to implement any of these techniques (outside of blipping).  Never owned a set of leathers, and I don't think they come in "girthy" anymore.

Theres still time though...    :yes:

Racing technology/riding style often gets quoted here but in most cases has little relevance to road riding.

This might help.... http://www.ridermagazine.com/motorcycle-gear-buyers-guides/big-gear-for-big-riders-buyers-guide.htm/

Hey they actually do!  Good to see manufactureres keeping pace with our bulging population.  I've lost 30 lbs over the last while and need to lose that much more to be in a decent "fighting trim".  Now all I need is the $900 for a set.   Maybe an Xmas present?

Aww really Noel , You have never pretended you are in the lead at a big race as you ride your FJ thru your favorite bit of road .. :gamer:

we all use race techniques to some degree when riding , granted not all the time but the relevance is there.

Haha, of course Mark. My point was, there are extremes in racing with riding style and technology that are impractical and unnecessary on the road, no matter how hard you ride or even when you can hear the roar of the crowd as you shoot to the lead through your favourite bit of road.

In my case, that would include banging it down three gears in a row with the clutch in while washing off 100 mph just to get into the corner 1/1000 sec quicker, knee dragging, remote front brake adjuster etc.

Well of course we don't need all that stuff , it would be superfluous Bling for the Fj .. However , how cool would it be to have some of it just in case.

Like maybe :

Linked braking system with adjustable proportioning valves .
slipper clutch for banging the 3 gear downshift. ( I will drop 2 gears but 3 needs some help on the Fj)
