Making a '14 and up YZ450 lighter?

26 posts in this topic

I'm debating a newer YZ vs '16 KTM 450. The KTM is $9300. I can get a '15 YZ for $6000. That's $33000 to do potential mods. Yeah I'm crazy and I already know this so need for bashing. A ti shock spring for $500, think seat foam for $300 and a used aftermarket exhaust on ebay for $500 for starters puts me at -5lbs. So the remaining budget is $2000. What to buy?

Where are all these bikes that people say they get for $6000-$6500 NEW?? Yz and WR's are all like $9000 out the door in my area and all around. I have read a few times on this site about bikes new at that price. I would drive to other states for $3000 and worry about reg later. I called all kinds of dealers even out of state (nevada) and could only get about a $500 difference. Is it that they are just finds that you come across or am I missing something??

I live in Ohio. Must be demand? I can't get a '16 for that of course but I can drive 3 hrs out of state and get a '15 for that with no tax. There was a dealer about 3 months ago blowing out left over '13 KX250f's for $4000 otd. It happens.

You would buy a $500 shock spring to save a 1lb, a $300 seat foam to save 500grams but skimp on a new exhaust? Bwhahahahaha

Please, just buy the KTM and save yourself the headache as you'll never make a KTM out of a YZF and vice versa...

Wasn't trying to build a hybrid. Both have +/-. Just looking for thoughts on making a YZ lighter. A ti spring for a YZ saves 1.5 btw. Not looking for bashing from a know it all j

As for spring weights, here is a reference. Slightly less then a pound in weight savings. And this is fact, not speculation...

You don't list which KTM 450, or the type of riding you plan on doing..

3300.00 is a huge chunk of cash, if you plan on MX primarily get the YZ450F hands down

and use the extra cash for any bling you want.. except estart

And sometimes "know it all's" really do know what they are talking aboot...

Disparaging references to nationality, ethnicity, gender, and/or other personal traits are personal attacks, and are a breach of both forum rules and civilized decorum.  I won't tolerate them here.

Trying to reduce the weight of any reasonably well built MX bike by a significant amount these days is an extremely difficult task.  It used to be a lot simpler.  I made a project out of my '72 CZ 380, doing things like going to bike shops with an angler's scale and weighing handlebars, drilling dimples in the back sides of engine covers and backing plates, holes in brake shoes, etc. Got 22 pounds off of it, but that bike came with steel fenders and a 9 pound gas tank, too. 

 

Anything or combination of things that drops more than 5 pounds from a bike like a YZ450 is very probably going to be very expensive.

I hated the genuine yam Ti spring in my YZ250. Too much rising rate. So lack of control and traction. To replace it, I have a genuine quality KYB steel spring. Same 4.9 rating. But nice constant real rate. So a huge handling improvement with the stock linkage. And it's only around 200g heavier. KYB can make amazing steel springs if they want to.

Don't give that guy from Think a dime of your money. Ask Monk and me about that. Buy the Guts seat if you really think you need it. I have one for my YZ and it's hard as a rock. Saved 1lb though.

There isn't much seat to save weight on with the YZF.

The best weight savings I every heard was to not put a full tank of gas in the bike...Only put in the amount your going to use during that trip/practice.

      Hi , I'm new here and I just purchased a spoke tourque wrench kit  "Excel (TWS-210ANS) 7-Piece Adjustable Spoke Torque Wrench Set" for my 2008 Yamaha  YZF450, the front spokes are smaller than the 6 that came with the bike and the rear spokes are larger than the 7 that came with the bike (I bought it New) Does any one know what sizes the front and rear spoke nipples are? I can still stop my order and seek the correct size somewhere. I find it lame that they gave me the wrong spoke wrench.
      Thanks in advance,
      Brent

      Hello everyone, you wouldn't believe the brain dead mistake I made. So I installed my crank into the right side engine case on my 02 YZ426F last night. (Keyword Night) Then I proceeded to install the left side engine case onto the crank and trans with the Tusk Crank Installer. All is fine and dandy until I realized I didn't put any Yamabond on the case halves.  Now the left side case will not come back off the crank for the life of me. Note: The first time I split the cases the left side case came off without any hiccups. I am using the splitting tabs built into the case by the way. Does anyone have any tips? Also, why is the left side case being so stubborn this time? I hope I don't have to order a case splitter, those tabs saved me $70!
