how many mph slower are they

[dalifts]

hey how fast is a 125 compared to a 250 ? Any video links ??? newby to the forum

[maf1188]

in mph i think there right around the same area maybe 5 mph im guessing but i dont know why everybody worries bout top speed top speed means nothing on a mx track or trails. jmp

[dalifts]

i am just riding trails. How many hp are they stock ??? I had a blaster all hooked up and im going to dirtbike now. a stock blaster is like 18hp. How many for a stock yz125

[maf1188]

right around 30-34 hp but it depends where you look.

[dalifts]

i got a choice. Of a 93 125, or a 92 250 both yz's what would u take

[maf1188]

well a 250 has around 40-50 im not sure and i know thats a big gap but its the best i can do. And if your just riding trails i would get the 250 because its got more power and a 125 doesnt really have any bottom end so its a lot of clutching but the 250 a little heavier. how long you been riding and what was your last bike and how fast do you plan on going.

last bike was a rm250, I just got rid of a race blaster, bored ported shaved head ect. I road a gas gas 300 quad. I have a gsxr750 street bike. I've road a yz125, and a 450f. IM 20 and been riding for 12 years

A 125 has 32-33 stock. A 250f has 33-34. A 250 has 45-46 and a 450 has about the same.

With correct jetting and being at sea level a stock KTM 125 SX breaks the 35 HP barrier, KTM 250 SX will break into 48 hp. A 250 thumper will break in at that 35 hp mark and a 450 will break into that high 49 and 50 hp.

[psycho393]

I almost forgot to mention that a 125 will stay really close to a 250 on flat ground in a drage race but if you add a hill in there the 250 will smoke the 125 simply because of torque.

Just for reference, here are some numbers thrown out from dyno of Doin' Bikes Lanesville.

[SirFallsALot243]

Word has it the ktm 250f has 40 hp out of the box :

[dalifts]

yea i know this sounds a little stupid. But anyway to lower the 250 like an inch ?? drop the rear down ??

[SirFallsALot243]

Not stupid at all. Many people wish to lower their bikes. 125's are actually a bit taller then 250's. I lowered my 125 by shaving down the seat foam. It takes 20 mins tops, and is easy to do. You can also buy lowering links like the kouba link, and ive heard of taking some metal out of the subframe. You can also lower it by adjusting the shock, and raising the forks in the trees.

[dalifts]

u know any links for those lowering links ?

[dalifts]

Yamaha YZ & WR lowering kits will NOT be available. Thanks for all your requests. ... thats what it says on there site
