Honda Spree and Elite 50 Forums

im sure this has been covered but im gonna ask it anyway

What motors can be easily swapped in to the spree frame?
by easily i mean cost, effort, pros vs cons... basically i wanna make a list of viable options for the spree

1: I kno everyones first answer is gonna be dio, dio, dio but lets see if we can figure out something new.
2: I was kinda thinkin maybe a ch 150d out of a elite but no clue if it works or if it would be even worth the trouble
3: Being a welder myself and growing up round racing I kno "u can put any thing into anything with a lil persuasion" but stick to the "easy" theme im talkin bolt up or minor fab work to do the swap.
4: Jus cus it hasn't been done don't mean it can't be done so lets get creative and do some research..k

Water cooled 2 stroke kart motor(gotta fit under the panels and keep cool so a free air is out of the question) on a custom swing arm, single speed chain drive.

could it be done with a dual varitor kinda like a stage 2 clutch uses two plates to achieve a higher stall and better friction idk if this is possible but hey never know;; that has a centrifical clutch should hold up, and with the custom swingarm leaves the possibillity of a wider rear tire for stability

dio,dio,dio

and there it is lol thankyou DAC

The wildest engine I saw was a YZ80 (or some such off-road 2-stroke) mated up to a CNC custom variator/clutch/rear wheel assembly. They removed the donor engine gearbox to do this. Should've put it in Adv Tech Docs... not sure where the pic is now.

Mopeds are easier to mod, they have swingarms like "normal" motorcycles so you can bolt in anything, run a chain, and you're done. Scooter require a custom swingarm/wheel assembly... PIA. A kart motor would require something like this.

A good start for a 4-stroke custom would be a Spree with a GY6 125 or 150cc air cooled motor from a Chinese scoot picked up cheap/free for parts. Problem is this won't be as fast as the wilder 2-stroke customs. I think it could be cheaper route to speed, though.

Im just messing around.
The dio is nice because its 2 stroke tuning at its best. But there is other ways...

I would be all up for a 150Gy6 swap. Those motors can kick some *. and can be bought on the cheap.

I wouldn't be surprised if a YZ80 modded like noiseguy describes would keep up or go faster.

its all fun and games dac lol

but yeah kenny heres a ms paint version of your kart engine spree idea i guess dont know how to get it on here [/code]

lol something like this kenny

the honda ruckus has a modular transmission, meaning it is separate from the crankcase halves, a simple adapter would mate almost any kart engine(kt100!!!) to it...and presto, a real racing motor with CVT!!!

KT100 would need mods for water cooling. I really dont see the need for a CVT, these engines propel a (much heavier) kart to a good 80mph with a cent clutch.

I was thinking of keeping the stock wheelbase too, it should all hide under the panels.

the go kart engine would be cool as *. But it would be a TON of work, and the cost would add up quick.

well isnt there that spree that was a radiator mounted up front i think i saw a pic of it somewhere but could u maybe biuld a swingarm that is kinda like those single sided ones on the bigger bikes and a very small chain drive to keep the wheel base mounting the motor to it as well

well hey, if your gonna do it, do it right huh?
