Author Message   Jaybirdxb12x Posted on Wednesday, July 04, 2012 - 03:00 am:        can some one remind me how many RPM's a 1200 turns at 70 mph   Tempest766 Posted on Wednesday, July 04, 2012 - 04:05 am:        In what gear and under what road conditions? There is no straight ratio. Mine cruises on the highway in 6th gear at around 3700rpms at 70mph on the flat straight-away...and my speedometer is off by about 5mph so it's closer to 4000rpms.   Ratbuell Posted on Wednesday, July 04, 2012 - 06:54 am:        My Ulysses is about 4000 at 80; right around 3500 at 70. Top gear, highway cruising, all stock.   Pons Posted on Wednesday, July 04, 2012 - 07:12 am:        JAYBIRD, I agree with Tempest766. I use my GPS as a speedometer on my last three bikes and have found speedometers are off about 4-5 MPH. @ 70mph I turn about 4K   Jaybirdxb12x Posted on Wednesday, July 04, 2012 - 08:53 am:        thanks guys you gave me all I need to know. once again Bad weather proves it is the most valuable place on the web for Buell owners and lovers   Pontlee77 Posted on Wednesday, July 04, 2012 - 09:06 am:        didn't know the Buell had a 6th gear   Djohnk Posted on Wednesday, July 04, 2012 - 10:58 am:        My speedo shows 3500rpm at 70mph in 5th gear (If I am going against a wind I feel like I'm lugging the engine a little, with the wind the bike likes it).   Cyclonedon Posted on Wednesday, July 04, 2012 - 11:39 am:        3500 RPMs at 70 MPH   Rdkingryder Posted on Wednesday, July 04, 2012 - 04:43 pm:        Around 3800-3900 at 70mph with the XB9 primary.   Datsaxman Posted on Wednesday, July 04, 2012 - 06:03 pm:        Tempest is dead wrong. It is certainly a straight ratio, and my XB12s also only have 5 speeds. Roughly 20mph/1000rpm in high gear.   Buelldualsport Posted on Wednesday, July 04, 2012 - 06:10 pm:        All you need is the gear ration, wheel circurfance, input the speed and you will have RPM. Like Dat says, it is a true mechanical ratio. http://www.ehow.com/how_6088311_calculate-rpm.html Follow Linkie (Message edited by Buelldualsport on July 04, 2012) (Message edited by Buelldualsport on July 04, 2012)   Buelldualsport Posted on Wednesday, July 04, 2012 - 06:13 pm:        An yes our ULY has only 5 speeds. Now the X1 had a Baker 6 speed, but that is another story! (Message edited by Buelldualsport on July 04, 2012)
