Which brings up another topic,

What's your method for doing a bat turn?

I've tired the turn the bars and chop the throttle, but usually only make it about 90 degrees instead of the full 180.

Does certain hardware make it easier?

I beleive it was Ralph that told me learning to do bat turns is important since its sometimes hard to find enough room to turn a rig around on a two lane road. Since I have been known to miss a turn now and then while riding around Maggie Valley I need to improve my bat turn skills.

(Not to mention number one son thinks they're pretty cool to do in the church parking lot when bringing him to Boy Scout meetings.) Cool

It may be the characteristics of my bike setup, somewhat front end weight biased that it is, but the technique i use is to initiate the turn in and chop the throttle, sometimes with a slight dab of the front brake to transfer the weight of the rig to the front end, which initiates the rear end to lose some traction and start swinging out. Once the rear end is swinging out, i usually lock the rear brake, which causes the front end to momentarily break it's grip with the ground, and allows it to swing around smoothly. I don't do this often, nor really practice it, but in the few times i've done it intentionally, it's worked well for me. *general disclaimer* what may work well for me, may in fact result in injury, maiming, dismemberment, or at the least extreme embarrassment of needing to ask a half dozen burly guys to help you pull your rig out of the ditch after you've effed up.

I did do it once, unintentionally, in a very tight decreasing radius corner on highway 141 heading towards the Cherahola near Deals Gap, right in front of a pickup truck of good old boys. It could have been messy had i not been able to power out of it 180 degrees in the opposite direction of which i started .. i got the feeling they'd have picked my bones clean.

I also forgot to mention, there is a bit of body english on my behalf to get the rear wheel to break loose when i've momentarily locked the rear brake up to initiate the 180 degree manuver. I'd basically do a sudden, sharp weight shift to the right to intiate the rear-wheel slide out to the right. It doesn't take much, as my 160 lb soaking wet mass is only facilitating the slide out, not making it go out of control.

JUST A WORD TO THE WISE (UN-WISE MAYBE?) . On a light rig with little lead doing these so called 'bat turns' with any speed at all can scuff up the nose of your batmobile or even put the sidecar over the motorcycle. If attempting this you are on your own and the results were tot5ally your responsibility. We can send cards Smile
Maybe it would be good to have a video camera ready ..LOL.
Oh..didn't Roger's rig have like 15" of lead dialed into it ?

Been practicing my "Bat Turns", you never know when it will come in handy. Everything about HPS is fun. Cool

My bat turns still are only making it about 90 degrees, I think I'm not going fast enough when I turn.

However after trying one in the Methodist churcg parking lot a while back when taking number one son to Boy Scouts, I keep getting requests from the Scouts to do "that thing where the back of the bike slides around."

I look at this as public service to get kids interested in sidecars. Big Grin

Could that be called a 'half bat'? Big Grin

Thank you, all. I've been told that I'm nuts and nobody does what I do. They're wrong. Now I wish I trailered my CBX's to Maggie Valley behind my Gold Wing EML conversion.

I know it's been a dead topic for a while, but after reading about this, perhaps a month ago, I spent a few minutes practicing bat turns with my MPS Goldwing/EML. Not very difficult -- I think the 135mm wide tires help a lot, since they don't have a ton of traction to start with. I found that with an entry speed under about 10 MPH, I could do a 90 degree turn with ease, but couldn't get past that. When I tried at around 15 MPH, I got a solid 180 degree turn, and if I tried any faster than that, I'd go over 180, although I don't think I ever got as far as 270.

This was all using the procedure of initiate left turn, followed immediately by chopping the throttle and grabbing the clutch once the rear wheel was broken loose (except that one time I forgot the clutch and killed the motor -- oops Embarassed ), and no passenger. On the road a few weeks later, I found myself in a semi-intentional bat turn around a very small roundabout, and when I saw I was going to slide too far around the turn, instinctually increased throttle and was able to recover mid-bat (so to speak) and motor off in the intended direction. It occurred to me later that it was pretty cool that you could "aim" a sliding turn like that, although it also occurred to me that I wasn't in a proper bat turn, since I was making a circle around an island.

Anyway, just another pro-bat post, I guess. Big Grin
