Svartpilen Weight Reduction Project

Right, that is the manufacturer webpage. But I can't order from there unless I'm missing something, they want you to go through a dealer, which I can't find that carries that part. If I go to the motormaster usa webpage there is a Buy Now button but the damn thing takes me to a 401 Forbidden page :confused:
 
Necro revival - where are people getting these rotors? I can't find an online source even with the part number.
Moto Master is relatively popular, have you had a look here:

 
Yes, see previous reply. If I go to the page you linked and click on USA it gives two options, both of which take you to a 401 Forbidden page error.
 
Newer models (I have a 2023, not sure when they changed) have a different rear sprocket, more mass machined out. I just weighed mine when I took it off, it was 966g. Replaced with 44t RS super lite aluminum at 320g

Pictures of the new and replacement sprockets please!
 
I'll have to do that later today. Another silly area, this kind of stuff just drives me nuts - the spacer for the top bolt on the front sprocket cover is clearly machined so they did the expensive part. Why use steel for this totally unloaded part instead of aluminum? Two minutes on the lathe, 20g down to 5g.

Thanks for the pics! Thats not bad for a stock sprocket at 966g. But the aluminum one is amazing at 320g. Please report back on how that holds up. I imagine it does well, these are not high power bikes!
 
I made a rear license plate mount on the mill because I didn't want to shell out the $150 for the projekt racing part. You can find them on ebay pretty cheap but they need to be modified for the chain adjusters and the axle hole is way too big so I just copied the design.

can you show us a picture of it ?

For your consideration:
Stock vs matte carbon fiber:
Front fender: 248g vs 81g= - 167g
Spocket cover: 135g vs 77g= -58g
Hugger: 162g vs 90g = -72g

Total weight savings: 297g
 
OOOh! Where did you get the CF parts? And does that military style bag have magnets in it?
Custom order from Bullymachine.it , but not a 100% straight fit so check my thread about the parts before ordering. The bag is fitted with Molle-straps, not magnets, but it works great.
 
Hi all, noob here. I’ve got a 2024 Svart on order. This thread was really helpful to get a general feel for previous gen platform. I’m sure there will be many differences versus the 2024, but likely a lot of similarities as well. The general ideas you’ve all had here are great though! I’m just curious, have any of you actually done the tubeless tire conversion? It appears that the factory rims and tires are compatible with a tubeless setup, the sprockets just need to be sealed from what I’ve found. Given the reciprocating mass savings and how far out the mass is on the wheel, I would have thought this was a top priority item for weight savings and overall steering agility. Has there been success with the tubeless conversion in this community or have there been issues with the modification? Thanks for all your helpful posts!

I wonder how much weight it really saves? Most of the installs I have seen use lots of sealant and tape.
You are right though... it is rotating mass. The flip side is the potential questionable reliability. Personally, I'm not doing some home made tubeless conversion.
There are also massive differences in tire weights. Might be easier to consider that first.
Maybe just use lightweight tubes? ;-)
More seriously, if you can afford it, just get lightweight wheels.
 
I did this on a cafe project. Not difficult at all and worked great. I didn't get the kit someone posted but used basically the same thing. These rims should be even easier to do than what I did because of the nice wide area where the spoke nipples sit. All you need is a roll of the thick silicone tape (forget what it is called), clean the rim surface very well and as you roll the tape down put a tiny bit of vaseline on the spoke nipple itself so that it doesn't stick to the tape in case you have to tune up the spokes later. Like most things, it is all in the prep work. A roll of tape was probably less than 10% of the weight of the tube and I didn't use a whole roll.
