Just a few comments here VryGry, intended to help you come to grips with this Spyder thing you're now riding. :thumbup:
Because of its 'Reverse Trike' configuration and the inherent stability that brings (even if you don't feel it...
YET! 
) your Spyder is really unlike just about anything else on the road, and with its suite of 'safety features' that we all so endearingly call '
the Nanny',
your Spyder will 'out-turn' AND 'out-brake' pretty much anything else you've ever even
seen driven &/or ridden on the road,
IF you learn to use the body-english necessary to counter the centrifugal forces that will seemingly be trying to throw you off to the outside whenever you corner hard &/or fast! Sure, you can plonk yourself down on a Spyder and fairly quickly come to terms with tooling around relatively slowly without scaring yourself or anyone else too much, but it takes a fair bit more effort & involvement on your behalf to punt one of these things hard and fast, and once you start coming to grips with how to do that, you'll
REALLY start to see the Miles of Smiles! Your Spyder's nowhere near as intuitive to ride as a 2-wheel bike, since you
NEED to actively turn the handlebars to corner; and when cornering, especially if you are cornering hard &/or fast,
YOU actively need to counter those centrifugal forces, either by bracing your core (in the low & slow, gentle stuff!) or by leaning your upper body at least as much if not more than you leant your 2-wheeled bike in order to safely make any turn! :lecturef_smilie:
The Spyder does not take just a little counter steering input to initiate a lean & then it'll do the rest, with a couple of dirty great gyroscopic stabilisers keeping you on thru the lean & turn like your 2-wheeled bikes do - you have to hang on and steer it all the way!! And since you don't mention the Nanny kicking in (and believe me, even if you might not notice one, some, or even
any of the 'little corrections' that she often does apply when you're truly riding hard, you
WILL notice it when the Nanny does an 'emergency intervention' if/when you ever get anywhere
NEAR rolling or flipping your Spyder! :lecturef_smilie: ) I can only assume that you really weren't cornering all hard &/or fast at all,
BUT BECAUSE you're not yet used to your Spyder &/or how well it
CAN actually turn when ridden appropriately, you probably didn't lean IN hard enough/far enough, so the centrifugal forces trying to throw you off the outside felt massive, which made you ease off on your steering, so you ran wide, and basically, your unfamiliarity and lack of confidence in the machine let it all get away from you!! :gaah:
The only real thing to get over this ^ is saddle time! Most new riders take
about 1000 miles OR MORE, to really start coming to grips with feeling comfortable on their Spyders, and for many, it takes far more than that to truly start getting the best from their Spyder's unparalleled traction, stability, and braking abilities! So be kind to yourself - 300 miles is nowhere near enough for most to even get comfortable on the seat, so don't expect too much too early, and don't push things too hard too early either! Give yourself the time and miles and gradually work up to going faster, cornering harder, and with coming to grips with the fact that
Spyder roll-overs are VERY RARE, and usually as the result of the input of
copious quantities of rider stupidity; too much speed & steering input while travelling in reverse; &/or the application of some external force, like being hit by a car or running up a curb! And even then, the Nanny will almost always kick in and do her best to keep your Spyder upright before things get critical, so if you can only hang on...
Once you start trying to corner harder &/or faster, start practicing leaning your upper body in and down toward the inside of the corner - try
NOT to push on the outside bar, as that tends to apply down & out forces up high on the bike, ie. with lots of leverage in exactly the wrong place, so it de-stabilises your Spyder far more than is necessary or desirable in tight corners, altho it might feel as tho it's helping you brace yourself better - but that feeling comes at a significant cost to your Spyder's ability to take corners at speed! So instead,
PULL with your inside hand on the handlebars, using your outside foot to brace yourself down low & to help you push your body weight across and lean into that pull; then lean in and down as if you were going to kiss your wrist! That'll work far better to counter the centrifugal forces and help keep the Spyder more stable without large inputs from the Nanny, and by doing that, I find most new Spyder riders, especially those with extensive 2-wheel riding experience, come to grips with the greater stability, traction, and cornering capability of their Spyders sooner!
Do all that for at least 1000 miles or so, gradually increasing you speed as your ability and confidence grows, and eventually you'll start finding the factory imposed limits of your Spyder - and I'm not talking about the relatively bendy chassis/frame &/or the deliberate de-tuning and restriction of the engine/driveline either - not YET, anyway!! Once you are feeling more comfortable with pushing a bit harder into the corners, your rear OEM Kenda tire will probably be getting fairly worn, and while your front Kendas will be wearing better, you'll start noticing that the tires AND the sway bar are not really up to the capabilities of the rest of the bike! Personally, I tossed those OEM excuses for black round things to keep the metal off the ground that they call Kenda tires as worn-out wastes of space within the first 5,000 miles, and fitted a real set of tires that far exceeded the Kendas capability in all respects, but then I did have access to brake testing skid pans & tracks that I was running my Spyder on fairly regularly, so the limitations of the tires became critical sooner than most, and only after that did I do a sway bar upgrade, followed by an ECU Upgrade that removed the de-tuning restrictions; but some like to fully wear their front Kendas out first - only I figure that just extends the time it takes to really come to terms with how great these Spyder things can be!
