2007 wr450f weit loss and bling ? Wht ya done to get weight down ? Alternative to blue attire ?

26 posts in this topic

Would like to strip off some weight, bike is stock, know about the 08. Yz pipe but other than that, what can be chopped off that's heavy ?

Also, keen to make the bike red and white but can't find red plastics and trying to do this on a cheap budget as the bike doesn't need anything really but keen to find cheap red bling, plastics and get some beef off her !

Ps, noticed a rhs side light rattle down low, are they prone to clutch rattle ?

Last WR was a 2 fiddy, thought they were similar but are actually very different upon inspection(engine wise) .

There are very few things to change to make any significant weight reduction:

-Battery

-Full exhaust

After that, you are just throwing money at a problem that can't be fixed.

Kickstand will save a pound or two. Idk how hard it would be to take the headlight off but once u did u could run the red and black yz450f special edition plastics kit, if not the bike will be red n black with a blue headlight. U can also take the oil tank off these and just turn it into a sumb pump type system like Paul Whibley n The rest of the factory Yamaha team does at GNCC races. It just lets u run less oil and keeps more of the oil on the clutch plates and u loose the pound of the actual tank itself.

All the weight you take off goes back on if you put a decent skidplate , bark busters, radiator braces and a steering stabilizer.

You can drop some weight with a lightweight battery, pipe and rear sprocket not much you can do other than live with it.

Got a motobatt fitted, will do the exhaust (yz or similar).

That'll do if the rest is a waste.

Where to buy those special plastics ? I can use vinyl for covering headlight.

What about this clutch rattle (I think that's it) , not a knock.

Bike has under 3000 miles and mint.

....it's just that there have been posts on this very subject now for over TEN YEARS so to us who have been around this forum, it's funny to see the same question asked over and over:

" How to I take weight off of an over weight bike, without spending a lot of money or time"

:naughty:

Well if that's license to be an arse, I am sorry to have posted something you've heard before.

You're an adult right ?? If you don't want to read it, ignore it.

There is no external oil tank on any YZF/WRF 400-450 other than the frame itself on the steel framed models. On the aluminum framed models, the "tank" is a volume built into the front section of the crankcases. Wet sump kits for engines originally built as dry sump systems are a terrifically bad idea, IMO.

If you don't like the content of a post, don't open it. If it disturbs you to see someone ask something that's been asked before, that's going to have to be your problem. I can tell you right now that it doesn't bother the site owners in the least.

There are far more constructive ways to point out a previous thread on any subject, and abuses of one member by another for failing to use the site according to your wishes will not be tolerated.

ThumperTalk has a rep for being a reasonably good place to get solid information. BS like what happened here is not how that came about.

My 08 WR450 doesn't have an oil tank. It has a sump built into the front cases.

The easiest way to strip weight is to shave some weight off of the nut that connects the handlebars to the seat.

If you didn't get that, I am saying that the most efficient way to remove weight off the bike is to lose a few pounds yourself.

Ha , yeah I did get it but at a fairly massive 10 stone/65kg/140 odd lbs, I am in good physical shape (play lots of sports for a 41yr old) .

Was just keen to see what could be removed this not really necessary , if you get my jist but I think I have it covered with the pipe and water bottle under rear, ignition set up, tail tidy stuff and maybe some bits and bobs.

Don't need it anorexic but hate riding a bike covered in unnecessary crap ! :)

2 posts prior to yours, if I lose more weight, I'll fade away ! :D

Anyway, bikes fine, they don't feel that fat to me for a 450 unlike the klx450r which feels like a tank but coming off a TM300, everything feels chunky.

CaveMike spend lot of time try take weight off him first 07wr450f. Him do lots of stuff, exhaust , battery, remove lights, take off coolant recovery tank, take off kickstand, do few other things. Add up to 10 lbs easy, and when him ride bike, him not really notice. Wr be big fat lady. If big fat lady lose 10lbs, usually still big fat lady after. Most times even if big fat lady lose 20lbs, her still be big fat lady after. You no try turn fat lady into skinny one. If sexy skinny lady what you want, go buy yz250 2stroke like CaveMike did. CaveMike also get almost brand new plated 07wr450, and him going let her be big fat lady her want be this time. Him no waste time or money on bike diet.

WR need 3 things before good to go:

Exhaust & jetting- these 2 really wake up fat lady, make bike faster and this help make it feel lighter

Suspension revalve- keep bike from wallowing at speed, bottoming out too easy. This also make bike feel more precise, turn better.

Those 3 make much bigger difference than if you took 15 lbs off stock bike.
