"I think the BMW is unique with the longer service intervals when on low power mode. But if I remember correctly it also has hourly service intervals when you switch to high power mode.
Very little info available of how this low/high power service intervals really work..."
IIRC, the increase between Low power map and High power map is 10HP, meaning from 40hp to 50/52hp...
most often a 'jumper' clip is in position behind side shroud, and removing/replacing this gives the change.
NOTE: high power map is DESIGNED to be used in conjuction with Akro slip-on, for better performance.
NOTE: whilst I have a handle-bar switch with Map 1 + Map 2, it is NOT switchable on the fly; you need to switch bike off, wait for headlight to extinguish (30 seconds) and THEN other map can be activated.
Bike is sold with THREE CS sprockets, 13, 14 & 15, I can only imagine trying to keep front wheel down with a 13-tooth in high power!
taken from ONE road test:
With the ECU circuit completed with the ‘power plug’ and the full 52bhp released, the 450X turns into a completely different animal.
In low-power mode it is perfect for fast trail riding and easy power, but with full power on tap there’s a big slug of horsepower on top that allows the BMW to rev out and stretch its legs.
On the faster, more open sections of the massive loop we were riding the 450 showed real pace, blasting across gullies without being intimidating to the average off-road rider (that being me.)
