my brother picked up a new 09 450r for cheap. I have a 2005 450r with everything that can be done it done to it. we went riding on the lake bed which was pretty much mini sand dunes. I took his bike for a ride and it was amazing. first off, it handled/steered amazingly. It felt so light and nimble compared to my bike. it made me lose a little respect for my bike. I thought my bike was perfect.. until I rode this stock 09. it felt smaller, softer, turned sharper, tires had better grip, everything. one thing I noticed on the 09 is its 2nd and 3rd gear definitely arent very strong... but im just used to my 05 which is stage 2 cammed, exhaust, intake, clutch, valves, yadda yadda. funny thing is when we raced the stock 09 450r kept up with my modded 05 450r!!! I dont know if it was because of traction in the sand but it even beat me a few times!!! so I was wondering. why was the 09 450r so much easier to ride and so much more nimble than my 05 450r? made my bike feel like a tank* riding the 09 kinda felt like I was on a 125 but with more power!!! * I probably have 50 lbs of aftermarket parts on the bike even though ive had my 05 for almost 3 years now. been through 2 top end rebuilds. spent about 15k on it and have everything that can be done to it, I thought it was prefect, I was totally happy with it... now I want to get a 09 or newer 450r!!!!
