Nev the WR450 with YZ cams is pretty damn close to perfect bike...that thing will sit on 130 plus easy , turns on a 20c coin, handles like a dream..and if you put super motard tyres on them they become insane...you can go round corners on your front wheel... you can put in a shorter suspension linkage and spring for short asses...or do what i do park bsied rocks, bumps etc, or put left foot on and throw right leg over as you start to move ...works a treat....I have this years model and its a seriously nice bike and so versatile...I could easily sit on the freeway, go racing moto cross, tour or cruise to the local pie shop and it does it all incredibly well.
I have owned so many bikes I am beginning to lose count and they all suck at certain things..but by far my favouites are the RGV250 for tight hilly roads like the Oxley Highway, blue mountains etc,,,the 2015 WR450 for offroad and most things, the 2013 KX450 for motocross and my 2010 R1 for fast touring on windy but open roads that ya wont get booked on... WR250 for tight bush tracks and enduro racing...
Worst bikes ever 2 x KTM 525 2012 2010 lots of torque but too slow to rev and twitch front ends...
Coolest bike to ride that was the shittiest in most aspects Harley I hired in Hawaii
Dream bike a sick looking custom chopper (not harley) with 350+ back tyre , lots of rake and a sick custom paint job.... (maybe when i sell the plane)
