Some bike handling properties do not work (unlike in Singleplayer)

[Fernando-A-Rocha]

Describe the bug

The issue that I am reporting below was already mentioned in this 2016 forum thread: https://forum.multitheftauto.com/topic/83945-bike-handlings/
Credit to RicardoMDS for notifying this bug that hadn't been officially reported yet afaik.

The following handling properties can be set (setVehicleHandling returns true) on Bikes (e.g. Sanchez; Quadbike is not affected, only 2-wheel vehicles) but have no effect although they should (editing these properties in singleplayer for Bikes works):

• engineInertia
• suspensionUpperLimit
• suspensionLowerLimit

^ These work totally fine on cars (tested).

See the code below on how to reproduce and observe the incorrect behavior.

Steps to reproduce

local veh = createVehicle(468, 0,0,5)--Sanchez
setVehicleHandling(veh, "engineInertia", 500)
-- expected effect: slower acceleration
-- actual effect: no change

In normal GTA:SA you can test changing such handling properties for a PCJ-600 (for example) and observe an effect.

• Edit GTA:SA Installation Folder /data/handling.cfg
• Find the line that starts with BIKE (for PCJ-600) and replace with:
• BIKE 500.0 161.7 4.0 0.0 0.05 -0.09 103 1.6 0.9 0.48 5 190.0 50.0 5.0 R P 15.0 0.50 0 35.0 0.85 0.15 0.0 0.15 -0.16 0.5 0.0 0.0 0.15 10000 1002000 0 1 1 4
• Check in-game that the bike's acceleration changed compared to default
