You know this racer land speeder stuff is out of my league to pay me much attention.
I know that on THE Gravel, of which some sections is similar fine grain loose layer on tarmac hard pack, compliant suspension keeps grip attached more than solid. Yet there does seem a speed threshold where tire just clips tops of ripples and misses some/most the in betwen lessor ones, so maybe a mute feature in long run. There are few straight-ish sections 200-300 yd long I can top 100 a bit before blind turns to back off below 80 or so, or no reserves to dodge the routine hazards. Tires literally dissolve on this play so don't do it no more.
Weirdly after 95 mph I can't keep tires in smooth ruts, they self climb like a belt
on a crowned pulley to the peaks of center berm loose pile, but then acts like slalom skiing which I'm rather comfortable with. As soon as front gets some weight from throttle reduction >/\</><>/\]<*>*> all hell breaks loose, like air plane rubber in front instead of rear, whoohoo! I've yet to try radial vs bias on the berm climbing phenomena, but its most impressive in accelerating turns when bike wants climb inside berm slope instead of the outside slope like Dayton banks. There is a crash like wave that goes through chassis as steering suddenly switches on it own to straight steering, then seems to continue in suspended crashing inward state, till I back off to fight the front ruddering like normal bikes.
When I've tried this on fat race tire SV650 it get too unstable to attain berm climbing speeds/grip. Narrow tires seem way to go fast on loose stuff.
Before I went through Peels suspension and drive train if cargo was sticking way out on one side [2 ft chain saw] or a cover or even my jacket flapping in breeze, weave/wobble would onset till I backed off or an interval of favorable wind gusts settled a while. I'm Way more concerned with ground effects in Fast Low Leans, not top speeds. Trying to visualize active air surfaces/shapes to either dump lift or press tire down more. We know why stubby air plane racers or cycle dust bin type ain't around no more, tail end vortexes detach and suck em back and forth. Side winds a big bother too I hear. I figured out a sleek land speeder but likely would need a rule change to allow, so would just have to run as out law for fun or terror.
