Not having even ridden an electric motocycle yet, I'm fully naive. With automatic transmission cars a common technique I've read about is to open the throttle with the brake held down and release the brake to launch. Does anything like that help launch the Zero motorcycles!

nope. Theres no torque converter to load up...
the cool thing, is you can just pin it from a stop. no clutch, no worries about going over backwards or anything.
the not-as-cool thing... is its not a overpowered wheelie machine.

its still fun... almost magical. like you're flying.

My FXS loses traction on the rear wheel if I go full throttle from a stop.

[Marcus]

Ok so I don't normally go mono however found that on FX it is relatively easy in sports mode while rolling at about 30 to 40 Km/h.  Ease the throttle for a moment and then turn it up again and it will power pop the wheel up.  Found this out by chance one time approaching red light then got green and the wheel went up unintentionally. Not sure about the road versions of Zero though as have nil experience there.

Marcus the FX is known as a wheelie machine (necessary for off road riding), its the other Zero bikes that are not.

Does anyone know the weight distribution on the front and rear wheel of a SR and a typical super sport?

My 2015 SR ate the stock front Diablo tire a lot faster (~4000 miles) than the rear.  The rear is still going (bald past the wear bars) at 11,000 miles.

really?

funny because i can whack mine wide open from a dead stop and not only will it not lift the front wheel, it definitely doesn't break traction. it's fast, but unless i'm on loose road, there is no slip other than on extreme angle.

and i know how to test a tire...



also just had my motor timed so i know it's not a mech thing...

laters,

Yes, I lose traction 100% of the time when I accelerate hard.

Usually It'll happen after 10 meters when there's a sudden surge of acceleration

You must love KFC because you already finished your chicken strips.   

[laramie LC4]

trying to get my hands on another set of wheels so i can put on some real slicks. then, those boy's at the track better start paying attention...

A reminder that the torque listed for gas bikes is for 5th or 6th gear, not lower gears, the gears multiple the torque, so an R1 has way more torque than the SR.

A reminder that the torque listed for gas bikes is for 5th or 6th gear, not lower gears, the gears multiple the torque, so an R1 has way more torque than the SR.

In both cases, torque is measured at the output shaft of the motor, so both bikes have gearing/torque multiplication issues to be considered. In another thread, someone suggested using thrust at the rear wheel as the standard, and I think that's a great idea. Perhaps even better would be thrust/weight, which would directly give you acceleration in G's. Five hundred pounds of thrust will accelerate 1000 pounds of bike and rider at exactly 1/2 G.

[laramie LC4]

according to my telemitry from sunday. my highest x-axis load was always on braking. highest was 0.55 at end of the back straight.

[MajorMajor]

laramie, can you clarify something for me?
You're saying that on your FXS, if you give it full throttle from a stand still, your rear wheel will not lose traction at all?

Also, is the bike stock and with the OEM tires?

[laramie LC4]

yup. easiest bike i have ever ridden "off-the-line", smoked an R6 2 times the other day. wait for light to turn green, weight forward, twist throttle. take off like a rocket to about 60 mph, then wait for the blue streak to go flying by once he get's up to speed.

stock tires, stock bike.
