External indicators of Puch horsepower?

Joseph Ferguson /

I'm going to check out a Puch Maxi tomorrow (this will be my first moped), and I'm wondering if anyone knows of any external indicators of the moped's horsepower. I know that one can determine horsepower by looking at the intake, thickness of the head gasket, etc., but I figure I shouldn't rely on the possibility of the current owner letting me take the engine apart in order to determine horsepower. I'd be happy with it if it's a 1.5 or 2, but it seems like improving the speed of a 1 horsepower engine is a much more involved a process (though do correct me if I'm wrong).

If it has the stock exhaust on it look at the number, count the teeth on front sprocket too.

Most 1hp has 13t front engine sprocket and 1.5 many times is 15 tooth, 16 tooth is 2hp on e50, za50 has 18x40 gears on 1.5 and 2hp, 1hp has 13 tooth front sprocket same as 1hp E50s;

If it has 1.5 HP well that’s OK too because you could make the pipe work but if it’s a one HP you got a change the cylinder and if it’s a two speed za50 you have to change the gears and clutch bell inside the engine or grind the a case to put a 21t sprocket on the front then put a 35 tooth on the back cutting, changing Chains and such just to get near 18x40 gearing

Any changes from 1hp and 1.5 hp to 2hp Will require intake changes and carburetor change or resetting/tuning

Re: External indicators of Puch horsepower?

It’s not hard to change a 1HP. So, that should be the minimum concerning factor in purchasing a moped.

I can’t resist.

- bald rear tire from doing sick burnouts.

- JEGS high performance sticker

- NJ license plates

- clamp on handlebars

Come on, what am I missing?

Re: External indicators of Puch horsepower?

I take it the sticker’s gone?

Thanks for all the input. I wasn't aware of the number stamped on the exhaust. And I'm not sure if it has the sticker or not; of course I'll check for it, but this moped seems to be in rough shape cosmetically, so I'm not counting on it being there.

Za50 Engine is,

A 1 hp Puch Za50 is internally geared restricted with very low gears and different not as good clutches,

Re: External indicators of Puch horsepower?

Welp. Didn’t know that. Since the OP said maxi I just assumed E50.

But that’s good to know. Cause I would like to mess with a ZA someday and it would suck to have to replace everything inside.

I usually look at how fast it goes

This is a pretty good indicator of power (edited)

Re: External indicators of Puch horsepower?

Take it for a spin real quick and go on a FLAT roadway with no hills. If it tops out around 20-23ish its a 1hp model. If it goes 25-27ish its a 1.5hp model and if it can touch and hold 30 its a 2hp. My Puch does 45-50 all day (but mines not stock its kitted) (edited)

Thanks again for all the input! Just checked out – and then purchased – the moped yesterday. It's a 2 horsepower Newport. Looking forward to putting in the TLC it needs to get back to good mechanical and cosmetic condition.

My bike has a 2HP sticker but 349.1.16.000.2 on the tail pipe which suggests 1.5 hp in the above chart. The reason I ask is I am checking out a bike later this week without a sticker and want to make sure I understand what to look for.

Re: External indicators of Puch horsepower?

Of you look In the moped wiki all the information is under the Puch engines.

Regardless any 1.5 or 2 hp is worth getting. Like it was said already, only the 1hp za50 two speed is restricted via gearing, all the others are easy to mod for power.

Also, za50 bikes require work before riding. They have rubber shift dampeners that begin to disintegrate over time. Run a bike that's been sitting for 20 yrs or more and you risk snapping the countershaft when they shift.

Also, if you do get a za50 bike. Don't ruin the cover gasket when you open it up to change the dampeners. It's width is built into the transmission and replacing it can destroy the thing...

.....just thought I'd warn you of some traps that have screwed people over...look into the differences in the wiki and you'll be fine

I understand I want a 1.5 or 2hp bike. I just don’t know how to tell what the bike has without the sticker. I have learned a lot about servicing my bike from this site but I am not a mechanic. I want to make sure a don’t make a mistake and buy a 1hp.

Re: External indicators of Puch horsepower?

I know dude, that's why I told you to look in the moped wiki.

Here's the article, just avoid this stuff... It's very unlikely you'll find a 1hp. They were the least imported...anyway, here's the link
