HOW TO DESRESTRICT A HONDA NSC50 VISION SCOOTER MOPED
Vložit

- The top speed of the Honda NSC50 Vision is in most countries restricted to 45 km/h. The restriction is done by a rather low gear ratio plus a rev limiter. The engine is however strong enough to pull a higher gear ratio. In this video a Polini variator kit that changes the gear ratio is installed.
Please note that doing this change to the scooter might not be allowed for public road use in your area, check local legislation before doing a modification like this.
An increase in gear ratio will however make the moped consume less fuel, if speed is kept at 45 km/h by the riders control.
Polini also sells a high speed variator for the NSC110. Doing such a conversion is very similar to what is shown in this video.

Tack för alla videos du lagt ut på Honda Vision. Var in hos en försäljare idag och köpte fil till motorsåg, blev även en Honda vision 50 2017 års modell 17 mil på mätaren. Nu kan jag serva tack för bra videos.👍💯
TACK! älskar min Honda. Tyvärr så han jag göra bytet innan din video :)
Bra jobbat! :)
Thank you so much for this video. I had my Peugeot kisbee two stroke stolen from me so I had to dig up my old vision that hasn't run in years. Your previous video helped me a lot to get it back running, but I had forgotten how sluggish it is compared to the two stroke. Was wondering if this variator was worth it and couldn't find much info since not a lot of people are interested in optimizing this bike, but now I have my answer ! Will give it a try and hopefully I can climb hills a bit better. I think Polini also does a tighter belt for the Vision, might give it a try too
Thanks, and good luck with your update. You are right, Polini has a belt that is rated at 769 mm instead of the original 785 mm. If they use the same standard for measuring then that might give a higher speed, if the front variator manages to pull the rear variator apart more. Hope you can come back with info on how your experiment worked out, it would be interesting.
@@hoojiesgarage1542 I will try that out and let you know. Did you notice any change with acceleration?
@@FoxMikeHotel Good question, no significant difference I would think, but it does feel quite a bit better to ride in general now.
Thanks for video ❤❤❤🎉😂
Tack för videon! Är det självfabrikat på den fiffiga plattan du använde för att hålla variatorn fast när du lossade på muttern för den?
Jag har också en dotter som kör vår Honda Vision och blev precis lika förvånad som du över hur mycket bättre scootern kändes att köra efter variatorbytet. Precis som du sa känns det som att den är designad för att gå 60km/h och orkar gå uppför minst lika bra med den trimmade variatorn.
Hi Tomi. Yes that little "cogged" steel plate to lock the variator I made myself. A card board was put in position first and with a pen I draw the outline of the variator. Then I "copied" that in steel. Interesting to read that our scooters perform the same 🙂
Merci
Dear moped riders, I'm wondering if there is a tuned set of cylinder and piston 70-90 for HONDA VISION 50 4T 2012 except for 3116518 Malossi Thermal Group 83cc. Or is this the only option to increase the cubic capacity?
Hi Urban. Not aware of any other cylinder kit. An option could be to buy a crashed NSC110 and "merge" the two bikes together.
Hi, thanks for the video! Do you think changing the spring is necessary?
Hi Viktor. The kit from Polini I bought second hand. The previous owner said that the speed increase was almost not noticeable but I still wanted to give it a try. As I went along with the installation I noted that the spring for the rear discs appeared virgin. I think this is the reason why the first owner did not notice much of a speed improvement. If the rear spring is not replaced, the new variator will not manage to pull the rear discs apart to reach the needed gear ratio. The front diameter of the turn that the belt makes needs to be as big as possible, and the rear diameter needs to be as small as possible, then the best change in gear ratio is achieved.
@@hoojiesgarage1542 thank you for your answer. I see. Its just such a hassle to remove the parts and screws are pretty stuck, was thinking about avoiding it, but I am gonna have to go for it.
Have you any tips on removing the bolts as those parts move when unscrewing which has made it difficult
Hi Connor. Which bolts do you mean?
Bonjour .
Je voudrais changer le roulement aiguille qui ce trouve derrière l'embrayage savez vous comment il faut faire pour retirer ce roulement en sachant qu'il y a l'axe centrale de l'embrayage au milieu.
Sorry, I haven't had to do any work like that on my bikes. I would just imagine that one will have to build a tool or two to be able to pull the old bearing out and to press the new one in. Good luck.
Hi, nice video thanks. I just bought the same scooter 2nd hand and the previous owner has already installed this kit. The scooter also goes 55-60 kmh but it is very slow at accelerating from a stand still and going up hill it is also a bit of struggle. Now I don't know how the stock version behaves so I would like to know if you had any similar issues or should I look for a possible problem somewhere else and what can it be? Thank you in advance!
Hi NG. The bike here runs uphill and accelerates as before, no noticeable difference. Maybe it is worth checking the engines compression?
@@hoojiesgarage1542 ok, what schould be the compression for the scooter?
@@ngg.7891 The easy answer is 10,1:1 but what that translates to using a compression meter I have no idea of. I think the best would be to make a comparison back to back with an NSC50 that is "good". Or simply ask the nearest dealer.
@@ngg.7891 hey, I have NSC50WH 2012, and think I've got a similar problem, what was the outcome in your case?
@@nameberry220 I have ordered a new belt and i am going to put the original vario, but i did not have to do it yet, as it is now too cold anyway.
Do you think it is possible to keep the scooter «legal» by using lighter roller weights (maybe 3 gram weights?) so it goes 45 kmh, and still keep the benefits of the derestricted variator? I thought this would be interesting for you to experiment with! Anyways, great video👍🏼
Hi JVB. Let me think. Lighter weights would have a hard time pushing the discs together at given rpm, so the engine would have to rev more to reach 45 km/h. Doesn't make sense to me, seems like one would end up with something pretty much like the original variator.
To maintain a lower rpm at 45 km/h, but not allowing it to go any faster, one would have to set the rev limiter at a lower rpm, which is not easily done unless you know how to program ECU:s. Or by adding an external control unit like on an A- or EPA-traktor.
@@hoojiesgarage1542 I was afraid that would be the case. My mother has a Vision 50 and she wants better acceleration, but doesnt want it to have any higher top speed because of legal reasons. Do you think there is a solution to this problem? I am leaning towards buying some rollers that are a gram or so lighter to see if that is satisfactory, but I am afraid it will loose top speed and slow down traffic even more.
@@JVBNorway Well, you can always experiment and see what happens. But if it feels really slow in acceleration, maybe there is some other issue with the bike? Low engine compression? Dragging brake?
Hi, where did you purchase the kit?
Hi Douglas. This kit I bought as a used kit. That person had not bothered to replace the large spring for the rear discs at the clutch, so he didn't get much of a difference in speed. But if you search for Polini 241.698 then you will find some online shop.
@@hoojiesgarage1542 Tusen Takk!
I would feel more confident watching if I knew you knew what you were doing...
The bike has been running flawlessly ever since the update was made. And this is CZcams, not an official video from Honda or Polini :-)
