Why are weights not listed for bike parts?

Id like to know that stuff too. Maybe vital should do a footpeg and sprocket shootout after they finish the a-kit shootout

If it is listed, businesses would close. Its as simple as that.

15% lighter than standard steel pegs...ok great mine isnt steel stock so how much lighter is it?
40% lighter than steel sprocket.

How about listing the actual weights?

Stainless exhaust $450
Ti exhaust $950
Is the 500 difference worth it? No clue, no way to even guess without knowing the weight savings as they are never listed. What are you getting for your money?

Same goes for hp claims. Ive seen some cam, exhaust, ignition bundle packages listed for specific bikes. They have to know the hp it adds or a damned good guess, and still no mention of gains...

while i do agree with you, the fact that they don't kind of tells you all you need to know.

I'm on the side of wanting to know weights. If I was a company making a decent product then I'd want people to know its weight.

i think the point others are saying is that if you really knew the difference in weights or the hp gain from certain parts, you wouldn't waste your money on them because its not as much as they want you to think, but this is exactly why I feel that they SHOULD tell you.

Sometimes you just need to break out the food scale or bathroom scale. For example, i compared the stock pegs on my Alta MXR to the Tusk Billet Race footpegs and they are 59 grams lighter each. Saved 1/4 lb and now have wide, grippy pegs!

Because not everyone gives a shit about weight. Most hobby riders would be better off getting a gym membership

Just shutup and buy it, peasant

I also would like seeing more transparency but I'm sure the marketing department says otherwise. They must be right because I bought without knowing any numbers.

2014 KX250f Stock- 8 lbs 9.4 oz



2014 KX250f Full Ti - 6 lbs (Saves 2 lbs 9.4 oz)



2017 KX250f Stock - 8 lbs 8.1oz



2017 KX250f Full SS/AL - 8 lbs 2.1 oz (saves 6 ounces)

If I want my 450 to be lighter I get my fat ass on the treadmill

But many people do, regardless of whether the bike will be ridden by a out of shape fatty or a skinny little fugger.

Myself, I'd like to know the weight of every tire out there, the lightest 1.6 x 21 and 1.85 x 18 rims, weights of spokes/nipples and chains.

And who will wind me up some one off titanium fork and shock springs?

I have an old long term project that I keep pecking away at and picking parts up for. Eventually it will be a 159 pound 76-78 CR125M Honda. Cool stuff, fun project and I may find me a ringer to race it at select vintage events.

I'm surprised nobody has started a website similar to what the cycling world has with weight weenies: https://weightweenies.starbike.com/listings.php

Weights listed for over 10k different components.

MTB industry does..

Remember the guy that bought the new Ti ProCircuit for his CRF250 2018? He put it on a scale and it turns out that it's pretty much the same weight as the stock exhaust.
Now would you buy a 1300$ Ti pipes if the ad also said that it's the same weight as the stock?

Also worth noting is that the Yoshimura was heavier than the stock pipe...

Weights are not listed as that would often contradict the marketing department's claims... We've been finding this out a lot in our KTM 150SX build (https://www.vitalmx.com/forums/Bike-Builds,46/Luxon-MX-2019-KTM-150SX-Build,1345731)

Example:

CycraLite Front Fender:
https://cycra.com/product/cycralite-vented-front-fender-ktm-2016-sx-sx-f-xc-xc-f-xc-w-exc-white/
"Lighter than OEM stock fender"
Actual weight: 585g

Cycra Performance Front Fender:
https://cycra.com/product/cycra-performance-front-fender-ktm-2016-125-500-sx-sx-f-xc-xc-f-xc-w-white/
No claims about weight
Actual weight: 533g

2019 KTM Stock Fender:
545g

Anyone want to buy a new CycraLite front fender from us?

52g doesn't seem like much, but find this savings in 8 different places and that's a pound of weight savings.

Horsepower is a different story and isn't quite as clear cut as weight. You'd really need to post dyno plots for comparison, peak horsepower numbers are highly over rated.

Regarding our products, we're currently revamping the whole website and plan to list weights for everything as well as the % difference from stock. Should be up in a week or so.

This is the weight of sx250 11-16 silencers

OEM Silencer 1770g -0
PC Silencer 1180g -590g
PC Shorty Silencer 1094g -676g
PC Titanium Silencer 808g -962g
Bud R Silencer 1050g -720g

Shut up and buy it peasant.... Gladly if i knew what it was i was getting.

And for those that dont care, great go hop in another thread. I wasnt asking if you cared or not.

And busting out the bathroom scale after spending 100s or 1000s isnt really practical either. Would prefer to know what im getting before spending it.

This is a great thread. Are the star cross 5’s really 1lb lighter than the dunlopmx33’s? I heard that in a podcast I believe. Anyone confirm?

Dunlop MX3SF Front (80/100-21) 3,950 g
Dunlop MX3S Rear (100/90-19) 5,060 g

Michelin Starcross 5 Soft Front (80/100-21) 3,520 g
Michelin Starcross 5 Med Rear (100/90-19) 4,430 g

Dunlop to Michelin weight savings: 1,060 g (2.34 lb)! And that's rotational (on a big radius) and unsprung.

In general, detailed specs would quantify how well-refined OEM equipment actually is.

Probably because you risk reducing sales of certain fitments when they are too far from the average. A pipe for a CRF250 may only be a couple ounces lighter, but on the KX450 it's a few pounds. Better to say an average of two pounds than to spell it out for every bike.

I just bought a Michelin Starcross 5 rear after the local dealer was out of the Geomax. This makes me feel a bit better! My old 06 300XC KTM probably needs the most unsprung weight it can get. Although this still bugs me out: My 2006 KTM 300 XC has a dry weight listed of 221.8 lbs. The 2019 KTM 300 XC has a dry weight listed of 222 lbs. Maybe I'll have to break out the bathroom scales.

It is so true that this is often not thought about. Is it because most sanctioned motocross racing has a minimum weight limit?

In the MTB game, the weight of any item is grovelled over, and a few less grams cost hundreds. Crazy that for moto it doesn't quite apply publically.. yet.

Maybe Vital could get onto this, would be pretty rad! Although, there might be a few embarrassed businesses that might put the brakes on such a story..

Have you happened to weigh a Bridgestone X30? I had one as well as a Dunlop (AT81, I believe it was) and the Bridgestone felt significantly heavier. Not sure how the AT81 compares to the MX3S or MX33's, however.

Actually interesting thread, would love to start seeing weights listed of parts. I think the exhaust manufacturers wouldn't like that at all though lol

yep, but alot of parts in mtn industry aren't machine specific,so manufacturers would have to list weights for every specific machine not just this derailleur or crankset weighs x amount. not saying it can't be done but its not as simple as the bike industry.

Unfortunately not, just those I posted. I can only add the following though:

4,740 g Dunlop D739 100/90-19
4,805 g Bridgestone M404 100/90-19
^Both new tires, but have been laying around in the shop for a few years

4,605 g Pirelli Scorpion MX32 Mid Soft 100/90-19

5,225 g Michelin Starcross 5 Medium 110/90-19
(The 110 is a lot heavier than the 100!)

This is weight i got on my tires.

Metzler 6 Days extreme 90/90-21 3898g
Michelin Starcross Soft 110/90-19 5242g
----------------------------------------------------------------------
Pirelli midsoft 32 80/100-21 3594g
Pirelli midsoft 32 110/90-19 5118g
