Just a quick one hopefully.. When taking a corner I might be in limbo between two gears and my brain is telling me it's not a good idea to shift during the corner. So my question is, what do you guys recommend;

- being in a higher RPM for the corner (so not shifting until corner complete)

- being in a lower RPM (shifting before the corner)

- shifting during the corner is okay

I'm already being very gentle with the throttle on a bend not to make sudden changes.


Cheers

You shift before the corner.

Racer's often used to have a reverse shift, so that on right handers they could up-shift whilst banked without stabbing the lever into the floor, which is legacy of the now usual left hand one down four up shift patern.

Roads aint race tracks; you should not need be banked that far; nor should you 'need' shift gear, really.. but if you do.. you aught have the margin to do it and do it smoothly without unduly unsettling the bike... if not, you are on the ragged edge long before and it's only dumb luck you haven't crashed already.

So, either a) you are over thinking stuff too much ad this shouldn't be a concern b) you are riding on the ragged edge, and whether to change gear or not, is probably the least of your worries c) you are such a goliath of innate natural talent (or accident looking for a place to happen) you shouldn't be doing it on the road. Which do you think best fits?

Be in the right gear before the corner. You want to have enough leeway in your revs to be able to alter your speed mid corner on the throttle, without braking or changing gear.

I always put on cool gear, not sure this helps with cornering mind.

As above, you should really be in the correct gear before you enter the corner. However if you find yourself way up in the rev range a clutchless upshift will keep the bike more settled than a slow clutch change.

You are overthinking it though.

Lower gear, go through the corner on constant, partial throttle, accelerate as it opens out, and only then think about shifting up.

Don't feel like you're chasing lap times, especially on a 125 with a tiny contact patch and Ditchfindertm stock tyres.

Same as, right gear first but on the odd occasion you do need to do it, doesn't cause an issue but then again, I have never down shifted a gear in a corner so wouldn't know.

Thanks for all the responses guys, appreciated.

I don't race lol nor am I in a racetrack mindset, was just asking for normal everyday riding, it hasn't caused me any problems but I just wanted to know what the accepted practice is for it

As already mentioned, unless you're on a track or riding on ice/snow/too fast then it shouldn't be a problem. Certainly a habit to try get out of though...

Definitely pick the right gear before you get into the corner. Definitely slow in faster out. Definitely keep the throttle partially open and constant whilst in the corner and then roll on more throttle progressively on way out. Definitely don't need to change gear mid corner if you get all of that right.

Getting the right gear before you go in forces you to assess the situation, polishing those legendary biker observation and assessment skills. If you can work out what gear will carry you through the corner then you have read the road, traffic, topography, corner geometry, road surface and myriad other factors and got it right; in doing so you have also built a pretty good dynamic risk assessment and mental map of the situation. If you steam into a corner and then start thinking about what gear you need, you are wasting processing time right at the time when you ought to be most focused.

Youll find as you ride more you get better at assessing entry and exit speeds and which gear you need, it becomes automatic and you stop finding yourself in the wrong gear. The aim though whether car, bike or HGV is to get your braking and gear changes out of the way in a straight line, then turn and accelerate out of the bend without having to change up until you're once again travelling in a straight line.

(Yes there are exceptions/advances on this, but as a basic rule it's fine)

I often change gear during corners, I'd say most of the time I shift down a gear so I can get more control and have more power.

Other times I shift up to save fuel because the car in front is going slow.

That'll be at least two gears lower than you should be in so that the back starts to squirm around when you let the clutch out while going too fast, such fun. Thumbs Up

Hi

Don't be scared to use the revs. If you get it wrong and are in too low a gear, then chances are that you still have a fair few revs before the red line

All the best

You're doing it wrong then. You should have all of your braking and gear changing sorted before you enter the bend/corner and drive through on a constant throttle then roll the throttle on gently and smoothly to exit the bend. You should be thinking ahead, looking through the bend, selecting the optimum line through and allowing for slower vehicles during this preparation.

This gives you predictable stability during the manoeuvre and far better control than changing any of the inputs while you're riding through it. Thumbs Up

I wondered who'd uprated that and why, but looking at the rating, it does make sense. Wink

Can't I predict how shifting down will affect my stability?

Sometimes while going round a left hand corner on the right hand side of your lane you may come across a puddle or slippy looking part of the road on the right hand side. What's wrong with shifting down for more power and using it to get closer to the left?

I'm not talking sharp corners as most corners you'll find day to day won't be tight.

Reversed shift so you can change up by 'stabbing' up rather than...erm... stabbing up......

I may be talking total bullshit but I can feel when my bike is going to slip, If I shift down the bike feels more stable, I don't see how it's much difference from using the rear brake.

No one quote total bullshit and cut out the rest

edit: I'm not saying you should brake on corners either but if you do then use the back.
