I just purchased an 08 yukon. I am no pro rider, I haven't ridden in 7-8 years. I wanted to get back into the sport/hobby to be more fit, do something with the family, and I do miss riding a bike. Ever since I got my yukon, i've been obsessing about mountain biking a lot. I even created a post about this. I originally wanted to get something more high end, but I did not have the budget at the time. Right now My yukon isn't letting me down in any way. My obsessiveness how ever is making me want to get upgrades. So far the main upgrade I think I should get is a new fork. The suntour xcr 100mm that came with the bike feels like its just a spring. I dont bottom it out, but when I take jumps, when it extends, it extends too fast and makes a loud clack. It feels cheap and springy. When I looked for forks, I also looked at other upgrades. I figure I can slowly convert everything to deore XT. Basically casette, derailleurs, shifters, hydro disc's, and crank. After I added it all up, I'm looking at over 1000$. If I were to do all these upgrades, would I be waisting my money cause of the Yukon frame ? I plan to also make the bike light, I cannot find the weight specs on it, but can I turn this bike into a rather light weight ? Also having a lighter bike really makes much of a difference for the amateur rider?
