I have a 2005 Strada RX150TE and the speedo is way off. Anyone have this trouble with their ride? My speedo is at least 10 to 15 mph faster than actual mph. What is the fix on this???

There are a ton of people on these forums that have that problem, including me. I find it absolutely ridiculous that it's gone on as long as it has. I wonder if the newer scoots still have this problem, both of ours are 2005, so I'm not too surprised. Do they not drive these things at all?

Mine is off as much as yours according to my GPS. Because I have a tachometer, I tend to ignore the speedometer altogether since I know 7,000 rpm is about 65 mph and every additional 500 rpm is about 5 mph more.
I have looked into the problem but for a mechanical speedometer run by a spinning magnet and a hair spring which works against the magnet there is no easy solution. The spring is too weak so it does not work against the spinning magnet enough causing the high readings. Replacing the spring would not be unlike fixing a pocket watch. It is not a job for the faint of heart.

I rode a Kawasaki 1500fi for years and the speedo was off 5 to 10. My Chinese scooters were always 15 off. Bikes tend to be off like that, I'm not sure why. My SYM 300i is pretty close although I haven't GPS'd it. However, it comes back to, what did you pay for the scooter? I know I paid squat for the Sino scooters. If the speedo is off, I just feel I got to suck it up and adapt like bnc did. If I paid a price like I did for the SYM, I expect more, and I got it. You don't get something for nothing. Chinese bikes are a steal, accept the paybacks.

howdy, yup, it seems the majority of scooters read 10 or 20% high. maybe you can make a mark at 50 mph from gps and just go from that. or at 35 , whatever is the most important speed for you.
lotsa miles and smiles to ya

Officer: "Excuse me sir, but do you know how fast you were going back there?"
Me: "Not really officer--- I have one of those Chinese speedometers."
Officer:"Oh OK, I'll just give you a warning then, have a good day!"
I usually have a pretty good idea as to how fast I'm going.
I'm just curious as to how much more it'd be for the factories to make a better one, or how much it'd cost to just swap out the old one with a new one--- say someone like scrappy or PFS sold an aftermarket speedo. It'd be something I'd think about buying that's for sure.

I think what I will do is use my GPS and mark my speedo lens at every 10mph increment. Once marked, I will then remove the speedo cluster and speedo clear lens. The new MPH marks will be on the speedo clear lens and I will use that to transfer, repaint and re-mark the MPH indications on the speedometers face. Re-assemble everything and clean off the speedo clear lens leaving a fresh and clean, proper MPH speedo that should be accurate by GPS standards. Maybe I will do some custom paint to the speedo face like flames or something while I'm at it.

If you decide to do all that, post a pic of it--- I'd love to see how it looks. |

They do that on purpose as the thinking is that it helps prevent speeding and accidents. Even name brand bikes read 5 to 10 mph faster than you are actually going. My Aprilia is less than 5 mph off so since it has a 100mph speedometer on it straight ahead in the middle is 45 (really 46/47). A few sticker dots on the lens indicating the real mph is all it takes and they can be removed with goo-gone and such when the get worn out/fade.

Sprocket, possibly the smartest man on any scooter forum, always recommended this aftermarket speedo and scorned you if you had a factory Sino speedo:

Its a hard sell to drop $130 to to $180 on an add-on speedometer while for many a $3 sheet of numbered dots will take care of it. The TrailTech stuff is very nice and holds up wonderfully especially in off road and adventure bike applications however it is a bit of overkill and way out of the budget of many scooterists. |

Agreed, it is steep. We had many folks use bicycle speedos as aftermarket devices. I'm not sure how they adapted them as far as wheel size but apparently they were adjustable. Some of them were under $30.00. I just put the TT out there as an option. I've used a couple of their products in the past and they are bulletproof. The quality and tech support is beyond great.

I just use my GPS, and memorize the speed mapping.
on my 50cc I didn't have to memorize anything. I knew that it's top speed was ~48MPH, and that's all I needed to know, because it took like what seemed like an eternity to get there anyway.
On 150cc's its more important to know; as you could very quickly be speeding.
On my TaoTao ATM150/EVO150, the speed was displayed correctly.
I would agree with some, just use a permanent marker, and mark down the correct speeds on your speedo; or use stickers.

Even on brand name expensive bikes you will find the speedo off , they always read fast , not slow . this is done so that say you are doing 50 in a 50 zone you are really doing a little under and will not get a speeding ticket which in turn would lead to a lawsuit in the land of sue everybody for everything . The manufacturer is just covering himself
