While watching a video on Thailand long tail boats, they included footage of their drag racing small displacement 2 stroke bikes. Iirc they were 125-150cc. Performance was amazing.
Here‘s a link. Watch worthy. When racing after they launch, many put up their feet and shift with their hand. Crazy bikes and riders!
I have heard stories about street racing in Bangkok. Not seen it myself.
This is many years ago i heard it 15 - 20
A Friend from School is working in Thailand and another Friend visits him Telling stories afterwards.
The story was that street racing was going on at nights at the harbor .
Maybe this type
Crossing roads was blocked and the racing going on.
I heard that the money part was significant Side betting which is popular in Asia
and at other places. Horses and so. Here is a stack of cash seen. And a Book Maker.
And maybe price money
Apparently attracting crowds watching and betting Then also.
The Police was there ..closing public roads for racing is of course something they want to check.
Directing traffic. Keeping peace.
So there was a part of that Cash stack that ended up in the Police forces pockets . If not No Racing.
Would break it up according to the story.
I once saw Road racing World Championships with small Displacement bikes I will never forget it.
They had many gears and the torque curve was such that the right gear and rev was important .Or it did not go fast.
There was a Spanish Driver with a much later brake point than the others.
After the long straight... flat out ..there was a 90 degree bend. . He overtook just before the bend
And then braking .He then himself got overtaken by the others that had put in their money on power instead of brakes. This was going on for many laps of the race and the Spanish driver at the end came in after the others.
There was a straight long enough for the others to go past him.
But the racing was more interesting than the big bikes then . More overtakings and more even Machines.
