Alright so I have a 650twin, which I bought to replace my 650 single. I spent considerable time on forums and checking specs after they were announced and released and I was very intimidated by the advertised seat heights... 30" inseam, former 650 single was 32.6 or something and advertised low seat was similar for 650twin (I just checked the tech data on the bmw site and it appears to have changed a little since the first models rolled out). Thus, I was worried a normal seat height 650 or even low seated 800 would be too high as I was already standing on the balls of my feet with the 32.6" Fsingle (not taking into account the narrower seat on the new models would better accommodate). Went to the dealership September '08 and they had a brand new 650twin sitting in the showroom and the salesman (dumbass) told me it was the low seat. The height felt good, test rode it, loved it, bought it. Soon after I realized I penis envy over the 800s and I also realized my seat was NOT the low seat, it was the normal 650 which means equivalent to the 800 with a low seat. So all along I could have just gotten an 800 if only I'd been more patient and a smarter consumer. It's really my fault. And what hurts even more (literally) is the normal height seat sucks, so if I'd gotten an 800 with a lower seat height my ass would be far more comfortable as evidenced on the 7000 mile return trip from South America I took this summer, and though not often, I wish I'd had the more off road capable 800. So it brings me to now. The cost to sell/trade in my fully farkled 650 to get up on an 800 would probably set me in the hole thousands. So would it be worth it (i.e. cheaper) to just beef up the current 650 with higher shocks and possibly a 21 inch front wheel and a low seat? How much would the 800 front forks run me? Jacking up the back, would it require replacing them? I don't care too much about re-gearing it, I don't much mind the current setup, I just want more ground clearance for the skid plate and a slightly improved off road performance. Thank you to anyone who can give me advice.
