Just what exactly did they do to chap your ass so bad?
that said, i've been trying to shave weight on my mtn bike lately, but it makes a huge difference in performance
Pit Row
When we made this bike we were definitely in the weight weenie category. Dropped chain to 420, rm85 rear hub turned down and wrapped with carbon, ti bolts,axles,pegs,subframe and exhaust. Carbon tank,side panels, fork guards, airbox, seatpan. Also have a big pile of suppose to be the lightest stuff money can buy we never used, like wheels and hubs then everybody gets heavy duty spokes and nipples on excels and talon hubs. About the only aftermarket thing that blew me away was that a full set of applied triples were .6lb lighter than stock 06yz125s.
I'm lucky that I even remember simple formulas like that... it's been a few years since I last did any flight instruction. Now I just let dispatch and the ACARS computer take care of all of the weight and balance problems!
A couple of ways I have saved small amounts of weight.
Full Ohlins suspension was 1.5# lighter but I did it for the ride obviously. I wanted a Ti spring but they told me that they worked poorly.
SM Pro Wheels, look cool and very slightly lighter than stock, but also much higher quality.
Tubeless, they hold up well and don't weigh more than thin tubes.
Pirelli tires are sticky and about 1# lighter front AND rear than Bridgestones or Dunlops.
Acerbis seat is supposed to be lighter, hard as a rock though. It's the only seat that holds up under me. I can destroy a typical seat cover in 2 rides.
I recently choose ARC composite levers over the Renthals because of lower weight. I also preferred the design and they were less $.
Cast Smartcarb weighs 1/3# more than a Keihen, but will be oh so worth it. I suppose since it gets better mpg you could fill your tank less.
I recently removed by little KTM cushion system (which had already replaced my FlexxBars) and in it's place mounted some Twisted Engineering CF bars. 1# saved and hopefully my wrists will like them.
I have a shorty Ti silencer. Not sure on the weight savings.
Things I have discoved is that Ti pegs are a complete waste of money. Since I can destroy a non-Oring chain and aluminum sprocket in like 6 weeks, I now run one of the fancy steel teeth rear sprockets and an O-ring chain are a must for me. Bike gains 2.1# with these parts and you can definitely feel it too. But I'm not made of money.
I have killed every expansion chamber known to man. I now run the FMF Knarly because they hold up well, but they are damn heavy.
Of course ditching the 4 stroke for a 2 stroke is the easiest way to remove 10# right off the top.
Also, my linkage KTM weighs 5# more than my PDS KTM and you can really feel that weight. But the linkage bike just handles better so...
Raptors are pretty damn big and they are pretty damn thick and deep...also...
They last a pretty damn long time, too.
You guys would have a Heart Attack if you knew the price of those HRC Ti pegs.
Just sayin' :-)
I weighed my bikes on a brand new 400lb digital shipping scale today and was quite surprised at what I found, my TM 450 with a full tank of gas (9.8L) weighed 246lbs, by my calculation that is only 230 dry, lighter than the Honda by 4lbs. Even with 9 sprocket bolts, ha! I expected it to be closer to 240. Claimed curb weight is 245lbs so I guess it's pretty much right on the money. That's bone stock with only the skid plate removed, no light weight parts on it. It made me wonder if the scale was off but my Husky CR125/165 on the same scale is a portly 215lbs with the tank drained, and I compared it to another scale and am getting the same readings with my fat ass standing on them.
You're about to celebrate post #10,000!
10K...hadn't even realized it!
See you guys at SLC!
Where we'll be puttin' some Ti on Colton Udall's #510 JCR Honda!
Either way my 314cc 2 stroke motor is competitive with the new 450s and weighs 15# less so I'm ahead of the curve.
When I powdercoated my frame they charged me for 4# of powder and they told me they used about 2.5# on the frame. So I don't know if that equates to a 2.5# increase in weight.
I've bought 2 sets of Ti footpegs and neither time could I even feel the difference at all. Even my feet couldn't tell. And they both got all rounded off and worn out. This last time I bought extra wide IMS pegs for like $90. Much better product and the 1/8# I gained is not something you can feel that low on the frame.
The heavier 0-ring chain and Ironman sprocket pretty much feels like adding a flywheel weight. It's very noticable. But the lifespan is so superior to the typical Renthal w/ a DID chain. At least 10 times the useful life if not much more.
