ride over 70 mph? hmm well I think I could best sum it up as smoooth! My bike doesn´t do anything it isn´t supposed to. I have some minimal vibration in the bars but I am adding iso grips from kuryakyn this spring and I hear that fixes the minor irritation. Other than that, I love my c50t it is the best handling, performing, sounding and looking bike I have ever ridden. Now that almost everyone makes cool aftermarket parts for the Volusia and Boulevards, you can truely customize the bike too. Go to my web site if you want to see my bike and some other customs ( www.bicidaho.4t.com ) and also check out Volusia Gateway at www.volusiagateway.us You should hear a c50 with the new 2into1 exhaust from vance and hines as well, before you buy a yamaha. If you get a c50 you will not be sorry. Good luck I hope this info helps.
