This is for the "newmann" and "R-acer" types in here that buy this kinda stuff...

When you go a spend a bunch of money to make your bike Lighter; but, then you go and add an Over-Sized Front-Brake kit...and you put some of the weight RIGHT BACK ON THE BIKE...at the Worst possible place...

Well, what would it be worth to have a really "light-weight" Over-sized frt rotor/brake kit?

I'm looking into this and thinking out-loud about the market for this kind of thing.

I've already proven that saving as much "un-sprung" weight as possible is the Best Money you can spend on a race-bike (From a Ti fastener perspective).

So, it really chap's my ass to bolt these bitchin' HUGE rotors on the frt of the bike after I've gone thru the task af removing all the weight that I can find.

For the record: Many of your Moto-Heroes HAVE to see a HUGE frt-rotor on their bike...

What is the difference in weight of a stock one vs the Over sized one ?

And what would what you would like to offer weigh ?

the difference in weight between a stock front brake and after market is minimal!

the spacer for the calipur might add 4 or 5 ounces if that, and the weight difference between the stock, beefy rotor to the slimmed down larger one, is actually less.

the weight difference is a push at the worst, the advantages in braking power or significantly higher though!

Ti front axle? And other ti parts:

Atomic 22 / Hickman Racing

515-285-4332

Ask for Jim or Tina
They have been at it over 20 years.

I don’t get obsessed over weight. (if I was I'd be on a 125 2 stroke)
I mean, if I am ordering an exhaust system anyway, I'll pay the little extra and get the Titanium version, and that might same a couple pounds.
But to save a couple pounds with Ti nuts and bolts would probably cost thousands, and unless you’re racing Pro, I don’t see the value.

The CRF450 is quite a bit lighter than the KX450F, but yet I didn’t really notice it when I tried both. Maybe it's because the KX450F has more power and grunt that it made up for it, not sure, but the KXF actually felt just as light (or heavy) to me.

I put a titanium front brake rotor on my 01 YZ250F. Came with a set of brake pads that weighed about half what the standard ones did. Trick components out of Canada is where it came from, not sure if they are still around. There is a company that builds all kinds of karting stuff that does ti rotors. Today though probably anyone with a waterjet could knock them out??

The ti rotor I put on was not a floating disc like came stock on the bike. What I was told at the time was that a floating disc was not necessary because the ti dispersed heat better than the steel disc and wouldn't warp. I have no idea if that's true or not.

TeamGreen what do you do?

Make lightweight components... carbon fiber stuff and Ti?

Just curious.

Yup.

As to weight savings: You can get 10 pounds off of a bike REAL QUICK with a Good Ti kit.

In 2008/2009 we were removing 25#s from bikes on a regualr basis...all the while we were adding Glide-Plates & Case protectors, Suspension, Brakes, Big-bars, folding-quick-adjust levers, etc. (Rememeber the 197# CRF250R?)

More importantly: You can get a coupl'a pounds (Each) out of BOTH the frt and rr unsprung areas.

It looks like it won't take much to remove .5 to 1.5 pounds out of an "Over-Sized" frt brake set; also, it WOULD be legal.

As to 500's Question: I'm still awaiting the answers on cost. I'm going to start with a Light-Weight Galfer Tsunami frt rotor that's been 'worked over' both in machining and materials and I'll take an entirely new approach to the Caliper Brkt...ALL LEGAL, too!

This crap is jus' too much fun!

Carbon is different because it can snap. A broken front rotor made out of carbon could slice you or someone else to pieces. Carbon shrouds aren't allowed (same reason)either and this applies to the GP's too.

Carbon shrouds ARE legal and there are All-Carbon braking systems on too many road-racers to count.

Carbon isn't as fragile as you'd think when it's made to last (With a proper resin-sysem instead of the cheap crap that's ooften used); also, there are Carbon ballistic panels on Gen-5 fighters/aircraft.

Carbon rotor carriers have been done, successfully, for moto: They were/are expensive, tho.

I'm talking Ti, here.

Hi M,
Your target market has to be the bubba beaters at( shhh.)...sandflea.net... *RIP* .....

Just make sure the order forms are large print and only accepted after happpyyy hour.

Ti will get Norman to the next step!

Are you doing any Maico parts? I here a 490 is he bestest works bike beater

Hope you are well

Heathen!

Have you been readin' my e-amil, again? (I'm actually workin' on a 490 for Vintage-Racin'...)

Ti couldn't get ANY Sand-Flea to "The Next-Level", DOH!

Btw, GinO says,"Hi!"

Hope all is well for you, too.

pm a brutha!

Ha!
I'm building a 74.5 400gp (vintage throttle control is drum brakes) and the only Ti on this thing is a strap on my dong so I don't get it pinched in the seat gap! Knee braces and an alloy tank is a pleasure too.

Pm your email I'll send pics

This is pretty cool. I'm anal about weight, not that it really means anything for me, but I just one of those hang-ups I have. I noticed when I put my oversized rotor on that is was heavier, and I got a feeling the front suspension acted differently, but I had some bind as well, so that was probably the reason. I have looked at the rotors I wondered if it was possible to shave of some weight. My QTM is damn thick! I'm guessing at least 1 mm wider than the OEM and I have newer consumed a rotor (a new rotor) so I figure you could decrease the width some, or at least be as thin as OEM or maybe 0,5 thinner?

I had this stupid idea to build some carbon subframe for my bike. Seems there are some cheaper carbon kits you can buy? I'm guessing that could shave of a pound? I will totally fail of course, but imagine how bling it would look! )

So these Ti kits cost what? 2k?

One thing I always do is run half tank since I will newer manage to empty one tank in a ride. That save me some serious pounds!!!

I build myself a set of Talon hubs/spokes/pro wheel rims for my CRF some years ago, and the rear wheel ended up weighting 3 pounds more than the stock Honda wheel!!!

Except ditching stupid aftermarket graphics (damn, there goes my PC graphics) and buying a Ti system, use thinner tubes and the right tires (they differ in weight) use aluminum sprocket what else can I do?

You know whats strange.....I have an 01 and a 06 RM250. The 01 is noticeably lighter than the 06 and I mean its a substantial difference. Both are basically stock....I cant figure out why a bike 5 years older than its predecessor and very similar would weigh so much more. I can literally pick up the 01 at the steering stem and subframe and hold it in the air but the 06 is a struggle. Still the 06 is a superior machine, I thought bikes were supposed to get lighter as they got newer? Please dont add any 4 stroke comments to this they are not even in the same league as my RM's Evil

According to the figures they both weight 96.0 kg (211.6 pounds). I checked more than two sites each. You might fill up the same amount of gas in the 01! Wink

Seriously, could be tires, and tubes. Thick tubes can weight 1 pound, and some tires are weight more than an pound extra. Add those together and maybe some less fuel, aluminum sprocket, OEM chain vs O-ring? Just there we have maybe 3-6 pounds?

I don't think they have added weight on the 06...

Dr both bikes are as close to identcal ad possible same tires both have same tubes same chains and sockets and gearing the only differences are the 06 has rad braces, platinum 2 pipe stock silencer and beefier showa suspension, the 01 has a lighter platinum pipe with a shorty no rad braces and lighter kyb suspension. Believe me I would've never posted w/o covering those items. I wanted the bikes to be as close as possible to the same so they might feel alike but they are a lot different.

The 06 does seem more stout and when suzuki introduced the 01 one of their biggest things was to make the 01 as light as possible hence the switch to kyb's after 00 they went a little crazy with the weight savings I can only speculate that The bike gained weight as the years came to make it more durable for sx racing. When riding it doesn't feel all that different but pushing the bike around and putting it on the stand its very easy to tell which one is lighter

Weight savings on a bike will only benefit when reliability or performance aren't compromised.

An oversized brake rotor stops the bike quicker but weighs more.... so whats more important to you ?

And a lighter bikes stops quicker with stock brakes. Imagine a bike 25lbs. lighter with oversized brakes. Plus, a lighter bike accelerates faster as well. It also handles better. As a matter of fact it does everything better.

Production Ceramic Matrix Composite brake rotors. When you pick them up it's like holding a feather instead of a rotor and is like 2# weight savings per front streetbike rotor.

I would contact them and try to get them to build you an oversized rotor for an MX bike. The fact that it is not legal for the Pro racing effects very few people that actually want to buy one.

You can save some weight by careful shopping as well.
-only buy drilled countershaft sprockets, aluminum rears, and choose your gearing by using smaller front and rears instead of larger.
-only buy drilled/ windowed chains
- Pirelli Scorpion tires are really light and hook up just sick
-the only aftermarket wheels I would consider would be tubeless Alpinas. The tube-liss system saves a small amount of weight too.
- Titanium shock spring is money well spent.
-Buy a KTM 2 stroke and save 30# just like that. My ready to ride KTM 250SX w/ heavy FlexxBars on it weighed an honest 210#.
