Motorcycles and stealth

Yes.

 

Yojimbo can't, however, use Cautious Movement while on the bike. So... 50% non-stealthy?

 

Hybrid bikes my dude. Gasoline for when you're on the move and and electric drive when you're sneaking. >:3

 

Electric bikes are a thing.
You have to put a playing card in the spokes otherwise nobody will hear you coming.

Can't do that with the hubless bikes the JSA use though.

 

I'm not too familiar with this level of lore detail, but I'd still be mildly surprised if anyone but Ariadna uses combustion motorcycles.

 

Why would any of the bikes need exhaust pipes if they were all electric though? :)

 

badassary :P

Exhaust aside, since most Infinity troops are equiped with sensing equipment of some sort, I am just assuming Yojimbo bike is equipped with tech that can mask its electric signature from proximity sensors (thus "No ARO in ZoC").

In short, "Stealth" does not equal "Silent" in pure sound form. It just means it has measures to keep it undetected.

As for the exhaust, I totally see combat bikes using some kind of sound projection at the minimum to project threat. Kinda like the sound of galloping horses...

 

... or "Flight of the Valkeries" projected on helicopters...

 

Like no one has ever done the "turn off the head lights and let the car coast into the driveway, so you don't wake up the parents" thing with a combustion automobile.

It's not unreasonable to do a cautious movement with a motorcycle.

 

Stealth is reasonable deniability, hiding behind common sounds or making no detectable noises or a range of similar methods while Cautious Movement is timing movement at the exact moment when the enemy is inattentive - they might see you but they are not prepared to shoot you the exact moment when you dart across vision.
I think it's entirely reasonable that you can't Cautious Move with a motorcycle because you will be locked in place so that you can't peek around a corner on the 'cycle which will also probably make increased noise prior to accelerating where a biological creature probably makes more noise when skidding to a halt.
(Unless a cat on a laminated floor... such elegance, such grace, so much skidding for so little speed gain)

 

well in N4 stealth will no longer be auto include in MA so we can guess that montesa and yojimbo will lose it

 

Kum bikers, possibly

 

I always imagined that Yojimbo knows how to stuff a potato up exhaust pipe to muffle it.

 

The current fluff entry for the Kum says they like their bikes loud. I don’t have my 2e book handy to see what it said during the monowheel era.
