Downshifting .. rooky question?

Hi All,

Wondering if its safe (for the bike) to downshift to 1st gear for tight corners on my GSXR 1000? I'm coming from the perspective of cars .. i.e don't use 1st for engine braking. Is this the same for a race-style bike though? There's plenty of near-hairpin corners on my favourite mountain ride where 2nd just just runs out of engine compression and all i have is brakes. I've done it a couple of times by mistake and it feels ok. I don't want to trash my box though, or invite a lockup !!

thanks!

Re: Downshifting .. rooky question?

I wouldn't recommend going to first. First gear on these bikes are designed for taking off... i.e. starting from a standstill at peak torque RPM for maximum acceleration. You will unhook the rear MUCH easily in first, in a turn. The gap between 2nd and first is taller than between the rest of the gears and I am sure you can hear the "clunk" between them when gearing down.

First gear is for taking off, only.

Downshifting into first around a corner is absolutely fine. I do it regularly through slower corners without any problems at all. I usually give it a nice blat to smooth things out and it's stable and controlled. I've gone 2nd to first even at higher speeds, no issues whatsoever. Doesn't 1st wind out to something like 100 mph?? So far, me or the bike haven't died.

I don't think I've heard of any bike at all being unsafe just because it's in first gear while simultaneously in a tight corner.

Re: Downshifting .. rooky question?

I would suggest that it depends on how experienced of a rider you are. Mechanically it won't destroy the bike, but it will be much easier to break the rear loose, especially on a larger displacement bike. Be aware of the road conditions as well. After the snow leaves up here, there is often a lot of loose, sandy stuff on the roads. If you hit a slick patch in first gear at higher RPM, a small twist of the wrist could end your ride fast!

Re: Downshifting .. rooky question?

I might wait for a few more replies before i slot it down to 1 for the corners regularly FYI, got the quickshifter on my R1000R and it didnt seem to protest at on those few shifts. 2nd seems sluggish pulling from the hairpins as the bike grumbles up to RPM. Copy that on the damp/leafy roads though. Re: experience, i 'think' im ok .. but all it takes is that one bad shift/corner.

Keep replying all !

Re: Downshifting .. rooky question?

What year is the bike? Has it got a slipper clutch?
There are some 5-10kph hairpins near mine, I mostly use 2nd and feather the clutch and Ive got to be careful it doesn't throw its head up.......But I'd never describe it as sluggish coming out of any corner is 2nd.

The bike has a 85Mph first gear itís meant for a lot more then taking off using first for slower corners is of course fine and there is nothing about first that would damage the bike at all

Get yourself an auto blipper to help make it smoother for you. This isn't really the bike to be learning the basics on.

Nothing wrong with learning on a gixxer. If he doesn't die he'll get it in no time; Hey OP, learn to rev match and try not to die trying or get the two way QS.

It's all going to be throttle control. I used to do 1st gear turns on my L3 all the time.

Re: Downshifting .. rooky question?

Its got a factory auto-blipper .. bike has'nt protested so far on the few downshifts to first that have happened. No blip needed for most of them .. im ok at matching revs to shifts generally.

It won't damage the tranny at all, but I would advise against it. On a liter bike it is much more difficult to control the throttle, you are either going to spin the rear or unload the front enough to affect steering and go wide on exit. Are you on the throttle well before the apex? I am betting you are losing to much corner speed which make the exit in second feel sluggish.

That is why nobody ride wheelies in first. It is much easier to loop. The higher the gear, the smoother your inputs are.

When I ride the mountains and there are all kinds of 10-20mph corners, I go through them at 30-40mph in second. Is it the fastest way, no. But we are talking street riding where that doesn't mean shit.

Re: Downshifting .. rooky question?

I wouldn't say i'm learning on it. Had a GSXR750 before it .. been a few years between though. More a technical question (will i break the bike) than a technique question. Keep the answers coming though!

Actually .. re-read my topic. Thats prob given the wrong impression. To clarify, I wouldn't consider myself a rooky rider .. just a rooky GSXR1000 owner.
