'Generell ist an der ´10er ähnlich KTM und GG ein Mappingschalter verbaut, der zwischen zwei Kurven wählen lässt.
Für die australischen Modelle ist zusätzlich ein Wahlschalter mit Feineinstellung dran.
8 Stufen für jede Zündkurve, wählbar wie die Klicks an nem Federelement.

Torque adjustment at the flick of a thumb? Just dial it in on the 2010 TM EN300
Trailriders are fast discovering the advantages of 300cc two-strokes these days, and a big part of that reason is the chug or scream engine – you can rev it or grunt it, up to you.
The good news for Aussie-spec TM EN300s is that they now come standard with a JRF Torque Control – as ADB staffer Ant Lyon enjoyed on his ’09 model – which, when combined with the two-stage engine mapping switch, delivers 16 torque options.
The engine hasn’t been changed for 2010, because it really didn’t need to be. The torque controller lets you tailor the engine to suit,
just like the clickers on your suspension – allowing you to fine-tune, rather than drastically alter the performance.
On my test ride, I tried from one to eight (the dial will look familiar to those who run an MSC steering damper), eight being the mellowest setting, one being the fieriest. I settled on three during my brief test ride, as it’s the best mix of scarey speed and tractable grunt for me, but eight let me get on the throttle harder and earlier in the tight stuff.
One part of the test loop was serious snot, but a quick flick to eight (with practice, you can switch it on the run) let me bounce up the gnarly bits like a rabbit on speed.
There are a few changes for the 2010 300 (see ‘What’s New’, above), but the bike is basically the same. That means the Marzocchi fork is dependable (though I preferred it once I had pulled them through the triple clamps one more line than standard), being firm enough yet still plush over the small bumps.
The rear Ohlins shock helps the bike track like a tram, and both ends respond very well to clicker changes.
The new fuel cap seems to have erased the ‘burning balls’ symptom of a leaking cap (as the ’09s could do) and the handguards are quality.
I know, because the trails I rode it on were tight, and I had to punch the odd low-lying branch out of the way.
The 2010 TM300 is a better and easier bike to ride than last year’s model thanks to the updates and, in particular, the JRF Torque Controller, making it a formidable bush-basher in the hands of experts and trailriders alike.
