A long driveshaft and heavy flywheel[1] mounted longways in a bike could have a similar effect, and I do remember people noting it when the K bikes came out. [1] One guy said that BMW had apparently welded a sewer lid onto the end of the driveshaft. [edit] Bah. I knew after walking away from the computer for several hours with a reply open that I should have checked for updates in the thread before posting.

When a driveshaft gets to a "certain length" or is required to handle a certain power level, they get lighter and more expensive, until you get past another point in length and power handling. It is all about reducing shaft flex, whipping, harmonics and twist. IOW, short low-power shafts do not have to worry about flex, whipping, harmonics or twist. The more requirements... the more "high-tech" they become. -- [link\|mailto:greg@gregfolkert.net\|greg], [link\|http://www.iwethey.org/ed_curry\|REMEMBER ED CURRY!] @ *i_wethey* `PGP key: 1024D/B524687C 2003-08-05 Fingerprint: E1D3 E3D7 5850 957E FED0 2B3A ED66 6971 B524 687C Alternate Fingerprint: 09F9 1102 9D74 E35B D841 56C5 6356 88C0`

How would it have torque steer? - (pwhysall) - (17) - May 27, 2007, 02:29:32 AM EDT

Monster-motored personal vehicles are silly. - (Another Scott) - (16) - May 27, 2007, 07:33:39 AM EDT

Nope - (drewk) - (15) - May 27, 2007, 09:18:11 AM EDT

"Torque lean", "Counter-torque lean", something like that? -NT - (CRConrad) - (3) - May 27, 2007, 09:42:48 AM EDT

On a bike, if you're leaning you're steering -NT - (drewk) - (2) - May 27, 2007, 09:55:24 AM EDT

Not if you counter by actually *steering* the other way. -NT - (CRConrad) - (1) - May 27, 2007, 01:20:03 PM EDT

That's every BMW ever, then. - (pwhysall) - (10) - May 27, 2007, 10:45:46 AM EDT

How does that work, then? - (pwhysall) - (3) - May 27, 2007, 03:32:12 PM EDT

No; just that like BMWs, they have longitudinal crankshafts - (CRConrad) - (2) - May 27, 2007, 07:25:38 PM EDT

gotcha, thanks - (pwhysall) - (1) - May 28, 2007, 03:26:08 AM EDT

Yeah, of course; they should never have started using it. -NT - (CRConrad) - May 28, 2007, 04:48:29 AM EDT
