YSR250F Testing

[sporkbiking]

What's the gearing on this?

[powertoweight100]

That little bike is fast. imagine a 2stroke swap

[iLOVEhairyASSHOLES]

yamaha should just sell their 250/450f dirt bikes, and plate them.

[pfiberoptik]

NICE!!!

is it street legal?

[1gunslinger4u]

Yes, It is plated & the 250F motor # is on the title as well....

[locomuyloco4]

hey your ysr its very very nice amazing you do a great job with it !!!!!!!!!!!!!

[tripletrash]

this thing has to be a bit of a handful with such a small chassis, but definitly a cool project. now try a 250 2 stroke lol that would be a highside machine

[1gunslinger4u]

Not so Bad... Very controleable linear Power band, unlike a 2 stroke... a 250 2 stroke would be dangerous.... I have my 450 nearly done...

[nfs5676]

is this a super pocket bike, it looks a lil bigger than a reg super pocket bike but smaller than a big bike

[1gunslinger4u]

It is Not a Pocket Bike... It is a Yamaha YSR 50, Similar to the Honda NSR 50 & Suzuzki GSXR50.... Get it...

[GP3PocketSnare]

should've gotten the R1 bodywork then painted the Fiat paint scheme.

[1gunslinger4u]

I don't like it.... But thanx for your opinion...

[GP3PocketSnare]

Thank you for at least valuing my opinion.

[1gunslinger4u]

Everthing is For Sale for the right Price, but I am not actively trying to sell it...Am working on another, Maybe when I have 2 I will be more motivated to sell 1..

[Rob2218]

is it for sale?

[stripervince]

yeah i know but they're just..........ya know...2 strokes. just listen to them. just smell them...the power bands, the sound, the feel.........the woody you get from hitting 3rd gear at 60mph and your eyes get pulled out of the socket...............sorry, getting a little emotional...gotta go and pull it now................

[1gunslinger4u]

True, Nothing quite like a 2 stroke, but still, I wanted to be different.... Working on a 450F now....

[kingcr3b]

oh shit, a 450f. I hand a crf450r before i sold it to a guy in niceville florida, that bike was gnarly! I had an aftermarket exhaust and a quickshot carb thingy and oh shit that was amazing!

[stripervince]

dont care if you put a 1000 gsxr motor in it,,you totally ruined it by not putting in a 2 stroke. i rode every type of mc imaginable for years when i lived in la. there is nothing that compares to a little kx 80 or a rd or rz or yz 125, or 80cc. they shreeek lovely.................

[1gunslinger4u]

Says you, 2 strokes are great, but nothing beats Thumper power, that is why you rarely see 2 strokes in racing anymore, Lovely is Old Technology.. Plus it is a Rossi MGP replica & they race 4 strokes now, so it looks kind of sily with the wine of a 2 stroke.... I have a Wayne Rainey replica withb a 2 stroke.. Get the idea...?

[sporkbiking]

Good looking/sounding nice work!

[WOTboy]

I'm pretty sure GP bikes with 4-5 cylinders don't sound anything like that.

[1gunslinger4u]

For Sure!! But I could only afford 1 cylinder... It is what it is.... GP bikes are much faster as well...

[ToadHypno]

Not to be a know it all, but if you are using the stock steel wheels, they will crack and fail with that power. I raced ysr for years in the 90', I broke a rear rim on a fifty, obviously from cornering abuse, but it eventually gave up. They make (back then) a nice aluminium wheel that we had to move to.

Nice bike BTW, and get some leathers and drag your knee, that last guy is dying to get his knee down...

[1gunslinger4u]

Well If you Knew anything, You would have Noticed that the wheels are not YSR wheels, Nor are they made of Steel...So there you go, you don't know anything at all...

[seafood360]

and the good lookin food u dudes were cookin lol

[seafood360]

great job man. love the rossi look too.

[dirtbikeah]

hey nice i bet it goes good i have a yz250f and it rips i coulent imagine it in a small frame like tht

[1gunslinger4u]

It is CA plated & road legal...

[fishnskate]

i meant was the swap easy or hard

[1gunslinger4u]

It was hard... Lots of fabrication, & figuring out oil sump, swingarm & radiator as well as lighting stator & exhaust...

[1983cr125]

is that the stock size of those 50s or did u change the forks to make it sit higher and back shock n stuff?cuz id liek to get one and put my dt250cc dirt bike motor in it its a 2 stroke but only has 21 hp but will still be fun

[1gunslinger4u]

The suspension has a 4" extended & braced swingarm with Fox YSR racing shock....

Front forks are stock except that a second spring was added (stock, only 1 leg is sprung)

Top c;amp is TCR...

[1983cr125]

alright thanx alot man and that is one nice bike u have to make another vid some time thats a real neat bike u should try to get it road legal

[fishnskate]

i have a 1988 ysr50. i want to swap the motor with a 250f dirt bike motor like you did. was the swap eay or hard please call me. 54-639-2669. help!!!

[DEFBOY35]
