Hey, just wondering how well the honda 110's fit in a fiddy? How much more do they weigh? Does it make wheelies harder cause of the weight? How much more hp do you gain? Im building a fiddy from parts and just got a 50cc, but wondering maybe i should resell it and get a 110cc? Is that to big? Is there a better cc engine to go with? TIA ~nick

 

a 110 out of a quad or trike wont fit. the cylinder head will hit the tire. use one out of a ct110 or u can order a lifan off ebay for under $400.

 

or build a 110 out of your stock fiddy


I feal it will have more nut than the lifan motor

 

Ya, I saw the lifan motors on ebay for a decent price, but its not a true honda motor, sounds like parts would be cheaper made or something. Is it better to go w/ a 50 motor and then a stroker kit, so you have the more HP w/ less weight....?

 

I believe a 88cc Big Bore kit and a stroker crank will add up to 106cc of displacement.

 

PM NiNeR he just did the whole big bore/ stroker 110 cc thing, he has all the details.

 

88cc Bore has a 52 mm diameter. uses a 52 mm stroker crank and it comes out to 110.43cc's.

 

81.2CC
Bore: 50mm (39mm stock)
Stroke: 41.4mm (41.4mm stock)
Compression Ratio: 11.5 : 1 (10.0 : 1 stock)
88CC
Bore: 52mm (39mm stock)
Stroke: 41.4mm (41.4mm stock)
Compression Ratio: 11.5 : 1 (10.0 : 1 stock)
95CC
Bore: 54mm (39mm stock)
Stroke: 41.4mm (41.4mm stock)
Compression Ratio: 12.2 : 1 (10.0 : 1 stock)
106 CC STROKER
Bore: 52mm (39mm stock)
Stroke: 50.0mm (41.4mm stock)
Compression Ratio: 11.8 : 1 (10.0 : 1 stock)
115 CC STROKER
Bore: 54mm (39mm stock)
Stroke: 50.0mm (41.4mm stock)
Compression Ratio: 12.8 : 1 (10.0 : 1 stock)
124 CC STROKER
Bore: 54mm (39mm stock)
Stroke: 54.0mm (41.4mm stock)
Compression Ratio: 12.8 : 1 (10.0 : 1 stock)

 

124 has 54.4 stroke I think, i know it has same specs as cr125.

 

damn, didnt know you could STROKE EM that high , thanks for the info tho!!!! ~nick

 

It uses a 50mm Stroker Crank not a 52mm

Dude my figures can be backed up by Classic Honda's
catalog pg 21 bottom left corner..... 106cc...like I said.

Largest displacement possible without boring the cases.

 

50mm crank is 106cc

52mm crank is 110cc

DRATV sells 52mm. i dunno what classic has

 

Yeah, what he said.

 

those are takegawa specs copied and pasted from two brothers
mine is 52 mm bore with 9.5 mm stroke
spanks just fine for me
bore(cm) X bore(cm) X stroke(cm) X .7485= cc's
wooohhooo mines 98 cc's

 

Anybody have the calculations in mm? I hate converting to inches. And zfiddy that formual doesnt work and you have more than a 9.5 mm stroke.

 

to do it in centimeters just move the decimal over one number ,mine has an added 9.5 mm is what i was saying which gives me 50.9 which actually makes mine a 103.01

formula works fine
on mine 52mm bore and 50.9mm stroke so move the decimal over on place
5.2X5.2X5.09X.7485=103.01874cc(cubic centimeters)
i didnt add the .09 last time i added
