Factory Team Bike Weights - Legal Limit?

I always wonder this too... Hopefully somebody in the know will chime in.

congrats with SLF motion too, stuff looks nice!

250 212 lbs
450 220 lbs

No. Some are close (red, white, orange), some (blue) are not.

Talking with Roger, he said that while they,re close, they leave some room for tire weight variance, etc.

Lets say that after you win, they weigh your bike with little to nom fuel in it etc. and you are at 219? Would you be DQd?

You would but RC wouldn't.

I remember DV saying his factory Suzuki was 240lbs. Of course that's back in like '08. Also a buddy and I did one of JT's Supercross Experience a few years ago, Short's last year with the BTO KTM team. When I asked about bike weight they hit me with 226 without hesitation. So they may not be right on the limit except for maybe Honda.

I take it this has happened before?

Shots fired. You mean to tell me JS7 should have been the champ in 2006?

With the availability of anything/everything Titanium, carbon fiber, magnesium, etc. (and their budgets), are ALL factory team bikes at the legal weight limit? Not sure what that weight limit is in the 450's, but maybe 220? My biggest question would be is the JGR Suzuki 450's at the weight limit? The Suzuki is obviously a heavier bike off the showroom BUT with JGR's capabilities, have they trimmed that much weight off of a stocker?

I was told a year ago that a production KTM was lighter or as light as the RCH Suzuki race bike (someone on the team). So based on that, I'm going to say no, they aren't at the limit. As far as I'm aware, Yamaha isn't at the limit either. I'd be surprised if Honda or Kawasaki was at the limit right now. Honda's electric starter setup isn't helping and Kawasaki starts by adding three pounds to their bikes with spring forks.

Why would teams not want to make them as light as possible, or are we saying that even replacing everything with Ti/Carbon etc, it's not possible to get them that light?

They make many changes that add weight. Like forks different guards , wheelsets etc. So offsetting the gains and then losing 20 plus pounds in some cases isnt possible im guessing.

It's not really possible...especially when some add weight with stronger rims, data logging, larger radiators, extra protection items, etc...

Not sure if it is true at all, but I have heard the KTM Factory Edition bikes are lighter than the actual race bikes themselves? Not sure if true as I said, but I could also believe it with all the extra protective parts, sensors e.g. that are added onto the bikes. (I know they shave weight as far as they can.)

Maybe ML knows?

Well if you can race a bike that's not available to the public, what's making them stick with weight limits?

The scale at the AMA truck, and the cost of getting caught under the limit?

What's the cost of getting caught racing a non production based bike?

Disqualification, in both cases, I'd imagine.

Don't they weigh the bikes without gas anyways? So the after race weight shouldn't change.

Chad reed said he likes the husky because of its weight. Add on the heavy duty parts and protection and still be lighter than the other manufactures.

RC wasnt d'qd for a fuel violation (he was d'qd but it was later overturned), the same violation that cost Reed the championship (to RC) the year before....

Pretty sure the regular production KTMs are lighter than the factory editions. They don't have the extra guards etc.

Just curious how much weight is saved using Titanium ?

Approximately 45% of the weight of the steel component replaced.

With all fasteners, especially axles/pivots, I’d guess about a kilogram (2.2 lbs). Some of it unsprung.
Every bit helps, and the main downside is cost.

Question: If you run a 350 (as Cairoli used to), do you get a weight break?

No. Counts as a 450, so 220 lbs

How close are we talking? a few grams? It would be interesting to see how fine they are cutting it. Seems like only the orange and white bikes can challenge the limit.
