1998 BMW R1100RT - Would I buy it again? Nope. It has been a good bike and done everything I've asked of it but after several overheating issues when stuck in traffic I'd like to go back to a liquid cooled I-4 engine.
2001 Honda CBR 929 - Am I glad I bought it.... YES! 11 years later and it still brings a smile to my face every time I get on it. Would I buy another one, no. My knees can't handle the riding position for more then an hour anymore.
