Congrats on the bike!
Good write up! This is what I have done to my 2010 FE450:
Cycra handguards and moved the handlebar to the forward position. I am 6 feet tall and this is almost enough to make it comfortable for standing, a bit higher would be perfect.
Mapping switch - the low setting makes a big difference for technical hillclimbs.
Husaberg skidplate, frame guards and exhaust header guard.
Bulletproof radiator guards - worth the money.
Radiator overflow tank, the bike pukes coolant easily.
I am thinking of an Acrapovic exhaust system to reduce weight and to let the bike run cooler and it costs too much money!
I am dialing in the suspension. The stock springs are right for my weight and gear. I have set the front forks to the sport setting and the rear to standard setting as per manual and this is better. The front was too soft and I was bottoming. At some point I will take it to a suspension shop to get it fine tuned!
I ride technical offroad only, but will have it plated in the summer so I ordered the blinker switch and wiring harness. I will put handguard blinkers in the front and flushmount in the rear.
The subframe fuel tank will be available soon!
This bike is a keeper, because it handles so well and traction is awesome!
