The only weakness of high engine compression I'm aware of is more heat dissipation but... 125cc engines possess such small combustion chambers that it can be easily addressed with air cooling alone; without the aid of liquid cooling and radiators! Now, if it was a 500cc or something close, then a radiator would've been more of a necessity! Mere 125cc engine displacement isn't exactly in the 'big bike' territory!
Us Pakistanis don't hesitate to mock new technology to defend our ancient and obsolete technology!
All YBRs share the same chassis to I think it'll be doable but I doubt it'll be ideal.
And yes; I mistakenly posted picture of a Thai Version of YBR. The Pakistani version doesn't possess disk brakes and alloys!
I'm not aware of any such problem with YBR, brother! I think you're a little biased towards GS150 as you're the owner of one and you find it disrespectful seeing someone indeliberately criticizing your decision and your purchase! Brother, don't take it personal.
You might be right. But unfortunately; I haven't had the chance to inspect one personally.
It may have lower quality but judging from the snapshots (posted below); I think it's STILL slightly better than The CG and GS! But again, I shall reserve my final opinion about The YBR-Z until I inspect one personally.
I won't be making further posts here to avoid heated arguments and skirmishes with my fellow PakWheelers.
I like YBR, you like GS. it's a free world and everyone is entitled to his or her opinion. Besides, its your money and your ride and I've no right to criticize your decision; but I do consider it my moral duty to persuade people to stay away from low-quality products with questionable reputation.
Good Day!
