First my bike: 1983 Honda XL600R, 9500 miles, stock, like new condition. Where I live: Burns, Oregon 5000ft elevation 60-85F summer. Question: This is my first Honda 600, I owned alot of bikes previous, anyway this bike has alot of torque it seems and will do about 85 topped out but takes awhile after 55mph to get to 80. I had a 1997 Suzuki DR350 and the 600 has more torque but seems about that same speed if not a bit slower. It is way way slower than a 2003 CRF450 I rode (but that was expected) It is defintely faster than a 1992 Yamaha XT350 I had. It will do wheelies in first gear if I sit back and nail the throttle... it wont pull up into a wheelie in 2nd unless a rock it hard and hit the throttle in mid-throttle range. I thought these things where suppose to be faster than this, considering everything I have read it should be a wheelie monster! It seems to run good, idle good, if I back off the throttle at 70mph it kind of surges harshly.. also going up a steep hill offroad in 1st gear under a load it kind of sounds like it is pinging? I am not sure, I havent checked anything on it, just bought it 2 days ago. SO are they suppose to be like this or what? 45hp, 320lbs it should go pretty good right?
