There's really no advice that can cover
EVERY possible scenario of this sorta thing, so you always need to do what you think is best at the time, given the particular circumstances facing you in this particular scenario...
But as a '
General Rule of Thumb', your best bet is to
ALWAYS scan the road as far ahead of you as you can, not just up to the back of the car in front, and then plan your path as you scan back to the front of the Spyder, do a quick scan of the mirrors & instruments, controls, etc; and then repeat the scan from as far ahead as you can see!
You should ALWAYS try to Look at WHERE you want to go, and NOT fixate on whatever you want to avoid! If you practice looking out waaay ahead and scanning back like that, things like these tire 'gators, pot-holes, or any other hazard or obstacle will be waaaay less of an 'emergency reaction required' surprise. Watch for things like cars ahead swerving, or the sudden flash of brake lights, anything that gives you a clue that there's something ahead that means you might need to take evasive action and start planning what you can do. If you've got the room and there's no oncoming or surrounding traffic that'd make it dangerous,
AVOIDING IT is always going to be your best bet!
Sure, if you're that close and you're going to hit it,
STOMP on the brakes as hard as you can
first,
THEN GET OFF THEM BEFORE YOU HIT, just to wash off as much speed as you can and so hit it as slowly as you can; and you get off the brakes before you hit so they aren't all locked up when you smack into it, cos adding a chock to already locked up brakes is sorta like hitting a concrete wall! :banghead: But
only do that
IF there's nothing following closely (you just checked your mirrors in that last scan, didn't you?!

) You'll be amazed at how quickly these things stop if you really
STOMP on the brakes - braking at its maximum with good tires and brakes in good condition, your Spyder will stop
MUCH quicker than anything else you've ever driven/ridden, there's a reason the RT Ltd's have a 'Drop Away' Foot Plate! In fact, you really should find a safe place to practice this 'full-on braking' thing occasionally, if not at least once sometime during the early part of each ride. You have one of the best braking systems available; a relatively lightweight vehicle with more contact patch & bigger/better brakes than just about anything else of its size & weight; and one of the most stable bikes available out there, so learn how to use all of that to your advantage properly! :lecturef_smilie:
But if it's too close to completely avoid safely, even after all your scanning and planning ahead and said braking;
then don't fixate on IT, look at WHERE YOU WANT TO GO and try to steer so that, in ship-driving terms, you '
Comb the Torpedo's Track'; or in other words, steer to run along the
length of it rather than hitting it square on with your Spyder's widest track/part exposed. Basically, you need to attempt to
turn your wide front wheel track either towards or away from the tire 'gator's widest section in order to attempt to go over it at the narrowest angle that you can. Even if it's lying right across the lane at 90° to your direction of travel, you should still try to hit it with one front wheel first, at a bit of an angle rather than fully square on; and if it's at enough of an angle and it's at all possible for you to swerve safely enough to do so, turn to let it pass thru the gap between one front wheel and the rear wheel, then do that!

hyea:
If you have no choice but to hit it and it's too big to hit with
ONLY one front wheel &/or avoid along its length with both front wheels, then hang on with your knees, tell your pillion to hang on if you've got the time, and
hit it with one front wheel first, then the other, and finally the rear. Sure, it'll probably buck like buggery, but the Nanny is designed to minimise the steering hazards this'll entail, she'll try to keep you going in the direction you've got the handlebars pointing, and you'll most likely be able to maintain steering all the time. If you hit it square on with both front wheels, it's more likely to kick the 'gator up under the bike and wipe expensive things under there right off your bike; you're more likely to get both front wheels airborne and so lose all steering for a moment or three; it's going to buck even harder than hitting it one wheel at a time; and when the rear tire hits it too, it's gonna buck even harder again! :banghead:
The Nanny will work very hard to try and keep things stable and under control even if you apply some sudden and fairly aggressive steering input; just like she'll work hard keep everything under control and maintain your steering if you brake massively; or even if you get one front wheel in the air a little. The Nanny on these Spyders is one of the better systems out there, even if you think she might intervene a little too early sometimes; but I can tell you from hard earned experience that she really does work pretty well in emergency situations when you start dialing in sudden and aggressive steering & braking inputs! But you hafta help by scanning well ahead and planning what you're going to do/how you're going to avoid in a way that minimises the Nanny's need to intervene. :thumbup:
