This sounds awesome.

Mark, Mark, Mark.

Keep digging that hole...

It's a race bike.

Use google and find out why it had such a light flywheel and the effect it had on fast revving. And you'll understand.

edit: Check out that piston...


Here's where to find the rest of the porn:

Actually, that's a bloody good question.

Aw shucks riff' thats awful nice a' ya'!

Have a look at this photo showing a few racing crankshafts.

The one on the bottom is from a Honda 125cc 4-cyl. while the middle Crank is from a 4-cyl. M.V. Agusta racer.

Anyone else have a theory? I reckon they're not one-piece cranks.

On the middle one there are what looks like the naughty bums of grub screws on the milled faces of the #1 and #4 counterweight/lobe area. Must have a separate crank lobe area thats key'ed and located by the screw? That the most straight forward way I could think of doing it and the pic seems to look that way.


Hey Mark, lets have a race, you'll win cos I'll just follow beeping and pointing you out to every cop we see! Not really freedom on a bike when you can get chucked in the slammer cos they breathalyse you on the way to the dairy!! Slow down dick, I'd love to go for a ride with you once you grow up. Love and I don't want to read your name in the paper. Mr Pancake.

Hey,

If they're anything like the honda RS125GP cranks, then no they're not one piece. The require very, very delicate hands and a very very well machined press jig to allow the big end pins to press in square and give the right spacing between the crank halfs.

I know the the principal is the same as the 2stroke single, but the art of pressing 6 of them pins in is well.... jaw dropping.

I'll go poach some photos off a website to give you an idea to the principle of how they go together

Yup, skiddys bike sounds better than that. RC149, that's a nice sound 125cc inline 5...

[Sketchy_Racer]

Some quick pics!

[R6_kid:Me]

Shit. When that thing picks up and goes, it really does pick up and go, especially for a 250!

I see mark has finally STFU, thank god. It sounds like a Lion ate a CBR1000RR with a slashcut...

I love the sounds of those old GP bikes, likewise the Norton Rotary

I see mark has finally STFU, thank god.:

I think he has taken his medication now, he seemed to be in a posting frenzy for a while there - every thread I went into he had filled with his written dihorrea and pics of his shit bike!

It's a 125...

[nudemetalz]

It's a 125...

and pulling over 20K rpm !!!

After watching the MotoGP bikes this weekend just gone, I've came to the conclusion that they're all starting to sound the same. The Kawasakis and Yamahas have that V8ish sound and the Honda, Suzuki and Ducati's have that RC30 sound.
You can't beat those 1960's Honda GP bikes for sound.
(Okay the Norton Rotarys around Isle of Mann ain't bad too!!)
