What happened?

Crash damage when riding motorbike_01 is much less than when crashing into the same objects at the same speed on motorbike_02. For example, hitting a fence at 30ish km/h on bike_01 will cause you to bounce back from the fence and do no damage, while hitting it on bike_02 was lethal. I've tested against multiple objects at various speeds and the results have been consistent, very little to no damage on bike_01, and badly hurt or dead on bike_02.

Reproduction steps

Spawn in both motorbike_01 and motorbike_02. Drive them at as close to the same speeds as possible into the same objects. Repeat with different objects.

    I've also noticed this but haven't taken the time to fully test yet.
    The damage/shock dealt across bikes feels very inconsistant.

    i've been testing with my own map, so results are a tad off from official expectations...
    But I was complaining to myself that I kept getting knocked uncon a lot on tiny bumps, and killed way too often during short tests..

    On a flat open road like in Chernarus this is not really an issue due to the flat open space..
    But when you try to navigate a course with many turns and obsticals...
    They just feel a tad extra painful than what they should be.

    Running the bikes around my map today...
    The bikes are colliding on things they shouldn't and wouldn't IRL..

    This is on my map and sure I could adjust this some... but I was going over 20kmph and should have cleared this jump...
    but the frame clipped and threw me uncon.. which I disagree should happen at that rate of speed.
    If anything it should be a bump....





    Using these as dirt ramps, the bike clips on the 2 inches of wood frame, almost everytime I go uncon and the bike clips into the asset



    I have yet to be able to make it a full lap with official bikes.....
    and I haven't even started adding stunt stuff yet...

    After further testing, it seems most of my deaths are when the bike lands on my foot after being thrown Rag doll off the bike and the bike is probably still in motion.

    Probably should change vehicle collision damage to be based on how fast the bike is moving (Shouldn't really be in motion more than 1kmph at this point....)
    So a sliding bike on top of a rag dolled player shouldn't be more than like 20dmg max..

    Now a bike traveling 60kmph sure... hurt me plenty... but it needs to be fair imo...
    Walking away from a bike crash is more rewarding than... "OH... a bike killed me again"

    but maybe give us some protection if we're wearing a helmet, pants with knee pads would be great.
    I've already modded my own server to give players 32% less damage if they have a Moto helmet on.
