:agree: There are places here in Oz where we pretty much
need to do that sorta speed
ALL DAY, only pausing for (short-ish

) fuel stops, or we'd never get anywhere! nojoke
These Rotax engines are more than up for it! In fact, the same engines are used in other applications/platforms where they
MUST run at or near their red-line revs for hours on end... and their red-line revs are somewhat higher than you see in these de-tuned versions our Spyders run, so there's
PLENTY of 'excess capability' there, and you're not getting anywhere near it!
So just cast an eye over your gauges every few seconds or so, as you should be doing anyway, and watch for any spikes in the coolant temp. But be warned, like so many other things, the temp gauges on just about all ICE powered vehicles these days have been 'dumbed down' so that they don't reflect what's going on in a real-time basis (cos it might scare the un-aware owners!

) Instead, after you start & the thermostat does its thing, the temp gauge indicator rapidly rises to somewhere near the middle of the range, then sits there, never reflecting the continual albeit relatively minor changes that
go on all the time due to the thermostat opening & closing; the radiator fans cutting in & out; changing power demands, gears, & throttle settings; any changes in the incline/decline; road surface variations; head/tail winds etc. et al; and only changing significantly when it's almost too late to react in time!! :yikes:
So that means that
IF you haven't been continually scanning the gauges, checking your speed, etc. & watching for spikes in the temp gauge &/or engine lights, oil warnings, yada, yada, yada; you just might miss the temperature spike that means riding
at any speed for even just another 30 seconds means you might need a new engine instead of just fixing a blown radiator hose or similar, topping up with coolant, and riding on that it would've meant
if only you'd been scanning that gauge every 10 seconds or so & you'd seen it rapidly rising or at least pretty soon after it hit the stop!! :gaah:
So apart from doing all the things you should be doing anyway, especially when riding at speed, you should be able to just ride normally, or as someone here often posts....
Ride More, Worry Less!
