THIS: https://www.youtube.com/watch?v=Wv8IPCE0LNQ is what remains of the raw footage I got running at Marulan Driver Training Centre, A neat little track south of Sydney NSW. Was a great day with a bunch of mates on bigger supermoto'd bikes and some road and even race built bikes turning up.
The good part of the one session (that didn't get corrupted) happens a few laps in after my mate on the XR400 gets past me, and then a couple of WR450s as well> Enjoy!
Currently has the stock rims on, with a metzeler lasertec 120/90 18 on the rear and a shinko SR777 90/90 21 on the front, I have no idea how these are but last time I was at this track I was on Pirrelli MT21s and these handle tar WAY better (didnt help I had way to much air in the pirrellis either).
Also on front forks with one blown seal and both with longer spring spacers and 10w oil. The rear shock is utterly rooted and the spring was at max adjustment when I bought the bike...
Personally, I think this setup works quite well...
This is how well the metzelers worked: http://www.youtube.com/watch?v=dIYv1g6TGos&t=1m35s
