Re: Bajaj Pulsar 180 (All Versions)
Oh wait I thought zma had 15t sprocket. Looks like I'm wrong. I need a reliable 15t sprocket.
Agree about the gearing. I'm looking for taller gearing.

I'm having problem with memorizing things post stroke but IIRC you have a P180 UG4 which comes with 14T front and 39T rear sprocket and chain pitch of .520, comprising of 104 chain links (Same chain sprocket as that of Pulsar 200NS).
You can use ZMA's 13T front sprocket which is a direct fit on both P180 UG4 and P200NS, but on P180 UG1 to UG3, they are not usable as the chain pitch is .428 (non O-ring chain).
You can go upto 15T in front sprocket on P180, after that there is no room left, on UG1 to UG3 you can go upto 17T, (18T could be possible but I don't know where you will get it here).
Below I have included a picture of P180 UG4's chain sprocket kit
On stock 14/39 setup, the ratio would be 2.786
On 13/39 setup (Using ZMA front sprocket), the ratio would be 3.000, which would be under gearing, meaning you would get better acceleration at the expense of lower top speed and lower fuel economy.
With a 13T setup you would be around 60kmph at 5k RPM while with the stock 14T setup, you would be around 70kmph (calculated in my head, not absolute values). Saddlesore is mostly about reliability and maintaining a steady speed over long distances, not about revving up and zip zapping. I'd suggest you keep the stock setup for SS, not because of reliability concern but because you need better top end for SS and exhaust note of a high revving engine (you'll have to rev it up more with a 13T to reach the same speed) is a distraction in the long run when the rider is comparatively more tired due to the long distance requirement of SS. (1,600 kilometers in 24 hours AFAIK).

At around 6000rpm Pulsars are said to have best fuel efficiency. I attained 52.6kmpl.
