GolfVenture Posted June 12, 2012 #1 Posted June 12, 2012 Was wondering with OEM tire size, how acurate is the 1st Gen Speedo?
KIC Posted June 12, 2012 #2 Posted June 12, 2012 mine shows about 5 MPH faster than my GPS at higher speeds..like from 45 on up. At 20 - 40ish it is 3-4 MPH higher than GPS. Seems to stay at the 5MPH variance at least up to 95ish ...
SilvrT Posted June 12, 2012 #3 Posted June 12, 2012 Was wondering with OEM tire size, how acurate is the 1st Gen Speedo? a 1st gen has a speedo?
MikeZ06Allen Posted June 12, 2012 #4 Posted June 12, 2012 Actually the correct term is air speed indicator for the 1st Gens and speedometer for 2nd Gens.
Yammer Dan Posted June 12, 2012 #5 Posted June 12, 2012 I am told if it reads 120 MPH you can't be doing that!!! All I know is that it is QUICK and I saw it run out of numbers a few times!! Thats my story and I'm Sticking to it!!! Read my sig.
MasterGuns Posted June 12, 2012 #6 Posted June 12, 2012 Unlke second gens, speedometers on 1st gens is a must. Scooters that can't reach a top end of 55 like 2d gens don't really need one. But their whine will go faster.
kevin5549 Posted June 12, 2012 #7 Posted June 12, 2012 I don't know about how close they are, but I have a BLUE 1st gen that goes so fast the wartering of your eyes distort the speedo. That is from behind the windshield. just a side question, these 2nd gens you guys talk about, are they the ones i keep passing on the interstate?
Pernese Posted June 12, 2012 #8 Posted June 12, 2012 I checked mine against the GPS on my trip to Baton Rouge last week and it was 2 mph slower at 65 than the GPS. My backside tells me I need to buy a gelpad before my next long haul though.
Flyinfool Posted June 12, 2012 #9 Posted June 12, 2012 Compared to my GPS the bike speedo reads 9% high at all speeds. I never thought to check the odo. There is a stretch of highway near here with a measured 10 mile section. That is where I always used to check my speedo and odo before GPS was invented. At the 55 speed limit it should take 10 min and 55 seconds to cover the measured 10 miles and the odo should read exactly 10 miles. I'll have to see if the signs are still there.
Max Posted June 12, 2012 #10 Posted June 12, 2012 close to bang on against gps... Pernese, sign me up for a group buy.
Dano Posted June 12, 2012 #11 Posted June 12, 2012 I go by the tach with my 1st gen, 2nd gen DON'T HAVE ONE.... at 8200 rpm in 2nd gear it says I'm doing over 75 mph..........just checked it last Friday before she goes bye-bye...... You MIGHT ask Muffinman.....
spitfire9 Posted June 12, 2012 #12 Posted June 12, 2012 Actually the correct term is air speed indicator for the 1st Gens and speedometer for 2nd Gens. LOL mine was off by 5 knots until I cleaned the pitot tube.
Stache Posted June 12, 2012 #13 Posted June 12, 2012 Was wondering with OEM tire size, how acurate is the 1st Gen Speedo? Given the time 1st Gens spend up on the jack being worked on, bike not moving, speedo reads 0, 100% accurate.
JohnMidnight Posted June 12, 2012 #14 Posted June 12, 2012 never needed to jack mine up yet but overall, mine with Venom X tires, pretty accurate, this is comparing from departure from my work, to home, using the route Google Maps dictated But I'd hazard there's a 1, or 2 mile discrepancy. I will point out something lovely... in my area... I seem to be the only Venture rider, everyone else owning a Venture, drives a cage to work.
Pernese Posted June 12, 2012 #15 Posted June 12, 2012 Given the time 1st Gens spend up on the jack being worked on, bike not moving, speedo reads 0, 100% accurate. Jack? Y'all seem a bit high tech to me. I just pick it up with one hand and flip the centerstand down with the other. Seriously, my 1st gen is minor maintenance and major fun!
MiCarl Posted June 12, 2012 #16 Posted June 12, 2012 close to bang on against gps... Pernese, sign me up for a group buy. Same here, at least at freeway speed. Never compared at other speeds.
a1bummer Posted June 13, 2012 #17 Posted June 13, 2012 Well last weekend after about 175 miles, the difference between my GPS and speedo was less than 1/10 of a mile off. I'd say that doesn't get much better. Bill
Venturous Randy Posted June 13, 2012 #18 Posted June 13, 2012 When I replaced the speedo with another one years ago, it was three or four miles per hour off. I recalibrated it and it is only off one mph at 70 according to a stopwatch and my GPS. RandyA

Keemez Posted June 13, 2012 #20 Posted June 13, 2012 how do you recalibrate them ? Read this thread, and follow MiCarl's info in post #13. http://www.venturerider.org/forum/showthread.php?t=14231&highlight=speedometer+needle
