125 cc

[Viper_05]

Heres probably a stupid question, but does anyone know how many horse power a 125 cc trail dirt bike is ?

 

[flyfishdoc]

Depends on a lot of factors, my YZ125 has nearly 40, but it couldnt be further from stock.

A stock DRZ 125 puts out about 7-10 HP, depending on who's doing the counting.

fly fish what do u have on your bike to boost it 10hp from stock? porting?

 

[flyfishdoc]

yea... everything pro circuit could have done to it, they did. Ported, polished, blue printed, new pipe, everything. A KTM dealer (and local racer) who's a friend of ours recently tried it out and said it was the fastest 125 he's ridden in his life.

My riding mower puts out appx 17.5 HP. Then again it's a 700cc. Too heavy for trails, also the suspension and clearance suck in the woods.

I have learned how to pull some really fast tight turns in the yard (it's all body positioning) and also like to coast it down the driveway and lock it up into a spin.

It's a bone stock mtd yard machine. Hope this helps.

vic, I think he may be telling the truth. Look around this forum, and you will see that he has had alot of upgrades done.

Unless one of the upgrades is a nitrous oxide injection system, I remain skeptical. :D

I'm not kidding have a look at my web page:

Next is a 9mm stroker crank with hopes of reaching 15+ hp

How do you like the works preformance shock?

Dyno's are straight out weird. There is so many variables when comparing them. I like them purely to sort things out on the bike. It can answer: Is that jetting better? Did that pipe produce more? Is that whatever? Simply dont take HP figures to far to heart. Its the rider, where it is produced, reliability etc, etc, etc, etc. Phils bike simply would be a lot more powerful than a stocky but less powerful than flyfisfdoc's. :think:
