Ofcourse sproketting Apar. Was running a different set-up for a Group B race. Final reduction is 3.38 on stock RTR, I was running 3.14.Originally posted by Aparajith View PostHow do u do that? Sprocketting? U know why am asking this ?sigpic

Can u explain what short gearing and tall gearing is....??Originally posted by Joel View Post

Yes, Exactly what I was suspecting!! I was noticing that these ZMA & Unicorn had less vibrations than Pulsar, Apache, Hunk, etc ... and I was suspecting this Short Size of Stroke for this ... Now, you confirmed it!Originally posted by Joel View Post
Regarding over gearing, you got even more acceleration by the freeflow setup, that's Good!
My question is - this data is based on a gear ratio of 1:1 ... right? Or is there another factor involved? ???The engine spins at 83rpm for every 1kmph. As opposed to 75-77 of most other bikes.
and Top Speed in 1st gear is 41, which is enough I think ...---

If anybody has ridden anyother short stroke single cylinder, u wont be talking about the vibes on the RTR. Ride a CBR150R, Suzuki FXR150, GF125 etc to know how a short stroke engine feels like. Just ride them and then tell me if they are super linear.
I got a chance to feel the CBR150R and the engine grunt and vibes were really evident. An R15 in comparision feels like a engine running like an electrical motor. Thats long stroke for u.
However in a multicylinder short stroke, the vibes are pretty much ironed out due to even balancing by supporting cylinders.
People used to cry about the vibrations on the GF125. With a stroke of 48.8mm, the vibes are very normal I would say. Max, u can have a balancer shaft to ease things a bit. The CBR and FXR also run balancer shafts to iron out vibes.
The R15 runs a balancer shaft to smoothen the engine further. Hence, it feels like a silent electric motor.
Also consider the fact that the RTR is the only 2-valve short stroke engine. All others in the example are 4-valve.

Dude, Short gearing is a "Setup" which results in good Acceleration (Pickup) but reduced Top Speed ...Originally posted by Racing Hart View PostCan u explain what short gearing and tall gearing is....??
Long gearing is a "Setup" that achieves more Top Speed & even Mileage, at the cost of some acceleration ...

@ Joel: Bro, kindly explain that RTR Gearing question I asked ... With a 1st Gear top of 41, it's good enough, right?---

The ZMA is the only long stroke in your examples. Hunk, Apache 150, Unicorn are square engines. Lets not talk about the vibrations of the Pulsars. This topic will head somewhere else then.Originally posted by Samarth 619 View Post
I didnt get more acceleration with a freeflow alone, It was a set-up with big valve head, altered ports, higher compression, bigger carb, freeflow filter, fully tuned exhaust etc. Even with a tall gearing, it was faster than any fully light weight Group D spec RTR that too with a light rider. From standstill acceleration to top-end.
The gearing is not 1:1 factor. RTR's 5th gear ratio is 0.88.
Its obtained from various variables. Nothing that we need to discuss about here. It was for reference sake.sigpic
