ULTRA-LIGHT 2005 CRF250R

[Terry_Blake]

OKAY GUYS, NO SMART#@$ REMARKS PLEASE.

I AM DOING AN EXPERIMENT TO SEE HOW LIGHT I CAN MAKE A 2005 CRF250R. I WANT TO DO IT WITH ALL AFTERMARKET PARTS AND VERY LITTLE DRILLING. MONEY IS NO OBJECT. (I'M NOT USING MINE AND THAT'S GOOD, CAUSE I DON'T HAVE ENOUGH)

PLEASE SEND ME SOME IDEAS ON REAL AFTERMARKET PARTS TO ACCOMPLISH THIS. I WILL LET EVERYONE KNOW WHAT I GOT THE WEIGHT DOWN TO.

IF YOU HAVE LIGHT PARTS ON YOUR BIKE LET ME KNOW THE ORIGINAL WEIGHT OF THE OEM PART AND THE ACTUAL WEIGHT OF THE AFTERMARKET PART.

THANKS

i believe that White Brothers Exausht ... carbon something... supposed to be really like ?

I hear that ti rear shock spring saves a few pounds and bolts right up.

[Heckler]

Just replace as much as you can with Titanium and Carbon Fiber. Met-Tec has some cool (but expensive) Ti kits for bikes that include axles and motor mounts etc. I have a Ti spring on my 450 and it saved about 2 lbs.

[FasterNU]

as they said.. titanium bolts everywhere. Carbon fiber for protection... light exhaust... etc.

I'd be interested to see the final result. I'm sure you could get that bike considerably lower than the AMA weight limit...... I wish i could afford to build one!!

[crfboy22]

how bout excels? arent they supposed to be lighter then stock ?

[Throttlejockey]

Excels are heavier.

[novaman64]

The actual rim is heavier but they make aftermarket hubs that are lighter.....

Thought I saw a thread on TT about Carbon Fiber "plastics" on a CRF.

Check out tires weights! I remember a few years back when one of the mags put a bike on a diet and they shaved some weight with perelli ( spelling?) tires.

Titanium, carbon fiber, shave the seat foam and plastic and use lighter grips ( waffle grips are heavier ). Also some of the after market plastic may be lighter as well? ?

[Heckler]

No way, I dont think the hubs are near as light as stock hubs. I have an Excel wheelset and the bolts used on the carriers are in no way light. If you changed them to Ti they may get close but even then. I think the only way to get a wheel set any lighter than stock is with factory works magnisum hubs.

Thanks everyone!

So far I have the WB Ti/carbon fiber pipe. What about Ti foot pegs are they lighter than stock?

Where is the best and most reasonable place to get the Ti shock spring? I have seen them and the prices are all over the board.

Thanks

May I ask a few questions, Is someone paying you to do this? and where are you getting the money from? I could always use a donation of parts if you have any that your not using! ?

[Heckler]

Try the TT Store. Send them a PM and Im sure they can get you one. They are made by RCS (Renton Coil Spring) They are sweet, and very light.

Terry,

It would be awesome if you could track your progress for us. Do you have acess to a decent scale??

Weigh the stock exhaust vs carbon fiber and report back to us.

I am not sure about the pegs. Tires and tubes can add weight fast.

Just ask me!! I run the Ultra Heavy duty tubes out of necessity(they weigh a TON).. and I also use the heavy Maxxis tires. Add that to the Pro-Rims and HD buchanan spokes.... VERY heavy combo compared to stock(but durable like I need!)

I'm sure you are aware... it's best to focus on unpsrung weight!!

Try wave brake rotors they take of alittle weight and help you stop faster.

Some aftermarket triple clamps are lighter.

[Throttlejockey]

Aluminum clutch plates, remove the backfire screen.

[Heckler]

Very few are, I think the Tag Matris clamps are. I know my RG3 clamps are really heavy...

Some aftermarket triple clamps are lighter.

[novaman64]

Applieds are lighter
