I purchased the bike about 6 weeks ago and its the beez kneez love it and havent fallin off yet, not sure if its going to hurt when i do ........!
Being the motor weighs about as much as you, yeah, it's probable going to hurt when you fall off. Good luck and be careful.
Thanks fellas i do think i should have gone with a 250 however will just have to persist and stay on more open trails for a while, the thought of the 450 seemed like the way to go when i purchased it, having the extra power the bike would do it all with ease and last for a good length of time.
You'll get used to it. I'm 48kg and riding a 610, which is no featherweight. I've found the best scenario is to have more than one bike, but if you can only have one, the bigger bike is probably the way to go. I haven't dropped mine yet, but my plan is if (when!) I do to not try and save it, because I certainly don't want it falling on me. And, I prefer not to ride the 610 alone, because there's no way I could pick it up myself.
They are a well planted bike and track well. Clearly you will have a get off at some stage but the bikes size is only a small part of the equation. Pick your lines well and stand as much as possible-it gives you leverage to change direction more easily. The power is there for when you want it. Maybe get a slower responding throttle cam that will tame the beast a tad.
