Honda Spree and Elite 50 Forums

Greetings:

They finally arrived! Paid by PP November 29 th and... They don't fit!

I blame myself, the oddball international nomenclature (why can't Honda-san stick with one name for a scooter anyway? Whoever heard of a Vision 2t Met?) and the Italian box that shows two different gear types on the same carton.

I'm not kidding. The front of the box, what I thought I was buying, shows this:




While the back side depicts this:




(The checkmark should be a clue... ) And the contents?




My knowledge is limited to what I've read here. Despite glib assurances from the seller that they would fit my bike, these appear to be for the '94-later SA50/DIO. Tooth count is 16/32. They were unbagged but appear to be in new condition.

Anyhow, on the chance that I may someday join the August ranks of the SA50-Dio owners, I'm thinking of keeping the 16/32 setup that I received. Never know when I'll want to do 80 on a scooter. Have to keep hunting for the elusive 9:1 Aero gears online.

what gears are avalable for a spree i have wondered

none.

wheelman, so what is final ratio on gears you received? LMK if you'd like to sell

i guess the almost 30 mph i get is all im gonna for now . i am gonna get out the welder soon and rebuild the stock pipe the 90 deg in it is ment for restriction. so ill curve that out and add this.....

i think the vision met-in is the same as the newer style 94-01 elite...nuts!

With the Aero's 12/34 initial reduction, the 16/32 secondary works out to 5.67:1. At redline that'd be close to 80 MPH! I'm not naïve enough to believe the
Polini 65 could pull that off!

I thought I was getting 16/40 for a 7.08:1 final ratio. Redline would yield 68 MPH. A guy can dream, can't he?

I have some experience with theoretical gear/ speed calculations. My Sportster has an aftermarket 30-tooth drive pulley on its belt drive - up from 29 or about 3% taller. This neatly corrects Factory speedometer error and my lightly-modded 1200 can pull redline for a 124 MPH true top speed.

My '84 VF 1100 could not pull redline in 6th but had its top speed of 157 indicated in 5th gear. It all boils down to horsepower curves and aerodynamics. I will post pictures of the Malossi 67-6458 kit tomorrow.

id like to see the pics

See above

From what i've read, NE50M Vision 1985-1990, NB50 Vision 1985-1987, NE50TH Vision 1987-1988, and SA50 Vision Met-in 1988-1995. Then there is the mini vision NT50, maybe the spree motor?

Greetings:

Thanks Evilone for the informative post and tasty pics. There's so much overlap in Honda's nomenclature it's easy to get confused.

I get that the 83-84 Aeros in the US first introduced the Variator. The '85-87 Aeros adopted the SE50 powertrain, but the '85 alone had some unique features - a 2-bolt manifold and different-sized tank fitting for the vac. petcock among them. Searching US Kelly Blue Book and NADA Values revealed you could get no fewer than THREE different 2-Stroke scooters from Honda in 1987: Spree, Aero, and Elite.

I have decided to sell the gear set 67-6458. See "For Sale" section in Forum. They're 16/32, or exactly 2:1 ratio - very tall for top speeds using a suitably powerful engine. You're on your own determining what they'll fit - photos will be attached.

these are the gears I got, along with the old gears that came out of it...they look the same? id take a picture of them in the scoot but that requires some level 2 dismantling

Greetings:

Yes those parts are similar. Mine are 300 miles away right now so I can't say for sure until Sunday night. It seems to me that my primary reduction - the clutch drive shaft gear - had straight-cut teeth, but as I said I'm not positive. Your box indicates a 16/32 ratio. I'm sure that's the same as mine.

It looks like you peeled off a 34-tooth 2"A" gear? That's the same as mine too. What is your model/year scooter again?

Finally, did it work on your bike? Did you have to machine anything or just press things on? I'm pretty sure I can remove & reinstall the countershaft gear if it's a straight non-splined press job. But how does the driveshaft remove/install? Special tools?

It seems like there's always an unbelievably expensive/unobtainable 20-digit Special Tool number keeping us from taking things All the Way Down.

shop press,not gear pulley

i used my beat up 10 ton harbor freight press to do the job, worked out fine, they are still turning smooth as ever....no special tools as far as i can remember, the long, splined, threaded shaft has a gear pressed onto it, which you have to press off and reuse, and there is another shaft with a gear which you press out and use the included gear...it does work, i am certain you got the same gears as mine...87 aero 50 right? i couldnt see two different gearboxes being produced in the same scooter line

i look at it this way, if the locals don't do it then its not worth it, anyone do the japan dio pulley conversion yet? did mine 8yrs ago on my stroker but if you do it on a 72cc bore you could gain some easy speed if you know how
