i am just about to buy a new 2005 WR 450F with full road kit, i am going to use the bike on & off road.
How often should i change the oil & filter if i am riding on the road?
any other help would be great!

Road use will be harder on the engine since you'll likely run longer as sustained higher RPMS.
I ride trails only and change every 100 mi. I thinks it's a bit more than necessary but I'd do at least that at first and watch the oil for particles.
These things don't hold much oil. It'd be nice if someone made a external add on tank.

i ride my motarded wr as a daily commuter
i change my oil whenever it starts to go dark brown
which is anywhere between 400 - 600 km/filter every 2nd (mostly a week or shorter)
average speed is 65kmh with alot of 80kmh freeway time (im geared so i lug in 5th @ 60kmh)
all good so far with 5000+ km
running motul 10/40 synth

1 day at the track or in the bush my oil is toasted pretty darn fast
i really dont see how road use is harder on engine, on the other hand the long wheelies cant be good :ride:
