I'm not sure if you can still get it. I know someone who tested one, and as far as road use goes, his opinion was that it (2WD) would be 'a good thing' for the average rider. It gives much better traction in the wet. The downside is it doesn't turn as fast, so while not good for racing, it may not matter for street use. As a bonus, now you can get punctures in your front wheel more often too. Naturally, negative attitudes to price, reliability and user perception will kill it off. Much the same as 4 wheel steering in cars. Tony -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
