mlin, why were you changing gear mid corner?

Probably should have been a bit more clear.

Was a downshift in advance of the corner as usual under hard braking (incl some trail braking as I came in hot). Turned in as usual then felt the lack of resistance/engine braking, so really not sure how it ended up between 3-2. But the initial command was done before turn-in.

Fun, the old false neutral. If forget did you bang the shifter up or down or did it pop into gear itself?

My R3 also gets stuck between gears from time to time and the gear indicator goes blank. I wonder if it's a Yamaha thing? I don't recall having quite as many issues on my Hondas.

Used to get that a lot with my 690, but could work around it by changing how I shifted. Normally you flick the shifter with your toe, then release clutch, maybe get false neutral.

But if you hold pressure on the shifter with your toe until after you release the clutch, no problem. Apparently, that’s the way you should do it anyway, but admittedly I’ve got out of the habit now with the dirt bike.

But might not be relevant on the track anyway. Are you even using the clutch to shift?

The quickshifter allows clutchless upshifts but you still need to use the clutch when downshifting I think.

HeliDriver · « **Reply #1726 on:** July 31, 2019, 01:21:33 pm »

I can go up or down on the dirt bike without using the clutch - just need to time it properly. But I’m not racing, so I use the clutch just because. Only time I don’t is when I’m exhausted and squeezing the lever is too much work.

But on a road bike on the track, I could see a clutchless downshift being a pretty intense affair. Would have to get your timing and revs just right for sure. Much more margin in the dirt.

I've forgotten to use the clutch a couple of times while downshifting. I don't know if there were any ill effects as a result.

Triumph introduced their new Rocket 3 R and GT with a 2458cc triple producing 164 HP and 163 lb-ft torque. The R is the purists' one to the right while the GT to the left has forward controls and a dinky little pillion backrest. The all new chassis allowed them to shed a whopping 90 lb of weight although it's still porky at about 700 lb.

That thing is giant, heavy and the HP is disappointing.

Neat novelty bike though!

I always clutch, and I'm good at blipping for downshifts even under braking. On the newer R6 the quickshifter is only up and even then you have to be deliberately accelerating for it to work. I've yet to ride a bike with a quickshifter on downshifts.

Technical flub, expensive high side. Crashes happen on the track. I'm just sad I binned such a nice bike.

I’ve never heard of a quick shifter. Guess that’s for full-throttle shifts?

This is a neat video. No quick shifter, just mad skillz.

Snowcat claimed that no one needs to clutch to upshift on any bike. I tried it a couple of times, kinda neat, might do it if I'm racing but I'll use the clutch otherwise.

Over the winter I trained on some mini bikes that didnt have a clutch. Close throttle, shift, reopen throttle. I do like having the quickshifter, it's fractionally faster than a quick clutch in/out the traditional way. The Ducati I rented back in March also had the feature. That and a slipper clutch are what I'm looking for, although the latter takes precedence, honestly. I'd love to bang off 6-2 downshifts quicker

. I was thrilled with braking power on the R6 because I'm a late braker and used it to pass others; but that also meant adjusting downshift timing.

Compounding things is the fact I'm used to inverse shifting (up for downshifts, down for upshifts) so whenever I get on a rental it's a mental fudge for a little while.

I clutchless shifted all the time when racing.

Under full throttle, pre load the shifter...then very slightly back off full throttle for a nano second and you'll get an upshift.

A friend of mine has a bike with a really good up and down quickshifter. And he says the problem is it becomes more like driving an automatic, takes a bit of the fun out of it.

yea, for a 2.5L engine, it's HP and TQ numbers aren't overly wowsers...if it were in a car, we'd likely give it a big yawn...that said, that's a lot of TQ for a bike...plus, it looks awesome, so there's that.

Crotch rocket hit the median. Rider wasn't too badly hurt, but the passenger is in critical condition.

I see a lot of heroes riding in full gear while their passenger is in an ill fitting hand me down helmet and little else.

Of course, there are plenty rolling around with no riding gear beyond a helmet.

@mlin32
Im glad to hear you're OK. It must have been a hairy moment for sure.

I'm generally a very calcuated rider on the track, a couple !! moments over the past years, but this was my first crash. I honestly wasn't too terrified. There was just that split second of "euh pas bon not ending well".....followed immediately by "c'est perdu" as I went airborne. I didn't resist or try and break the fall (honestly no recollection of how I impacted the ground); just dropped and rolled. Got up, no chance in righting the bike, and scampered over to the flag station.

I really hope I didn't fracture something in my heel though. I can walk, the limp is mostly gone, but if I put weight on small spot, it hurts like the dickens.

Well....I've got about 1500kms on the new scoot......and I got my first MIL light...an ABS light.

German vehicles are crap.....

they seem unable to master the simple, little things....
