Re: Pulsar 200 NS Owners Review and Experiences

Brother is it possible to explain me the concept of gear ratio?

Re: Pulsar 200 NS Owners Review and Experiences

To put it simple, gears help multiply torque. Unlike motor that run by electricity or stream, where it can produce max torque at all rpm say 1 to 3000rpm. Thats the reason why or locos(train) are hybrid(burn diesel and generate current to run the traction motors, because trains weigh around several 1000tonnes and you can't expect torque coming max at certain rpm only. But we can't do that bikes or car as electric motor seems not proved yet and convenient. So diesel/petrol engines cant handle direct load. Try taking your bike at sixth gear. The engine will die because it can't take that much load as the connected load is 100% now. Try riding a gear cycle in 7th gear, and the effect. Do the same on 1st gear and feel it.

Lower Gears will help your engine to generate some torque by reducing the load initially (increase engine spinning rate to get torque, as these engines characteristic is to get torque at certain rpm)and gradually increasing it to max to get the max speed.The gear ratio will always start with 1st gear using 3:1(3 rotation of crankshaft by one rotation of the final sprocket cog) and at final (sixth gear)you will see 0.9:1 which means every rotation of the engine, you can expect the same rotation of the final gear going to the tire. But why 0.9?. at 4500rpm in sixth gear, then (5000x0.9= 4500rpm) for every 4500rpm of cranck shaft, the final front sprocket will spin at 5000rpm. This is taller, which means it will provide more room for the rear sprocket even if the engine is running at max, thats why pulsar does not hit rev max at the top gear. It depends on manufacturer. In theory, it wont saturate. These numbers are just for assumption. [emoji2]


Now what is sprocketing?, you cant change the gear ratio unless you redesign the gearbox assembly. But you can easily change the front and rear wheel sprocket which is the final ratio. Hence this will affect your rear wheel spin rate seriously. Changing 14/39=0.35 to 14/41=0.34 means For a 9000rpm on engine crank, (0.9) 10000 rpm (from secondary) the rear wheel will spin 3500rpm on 39T and 3400rpm on 41T

Hence on 39T the bike gets 100rpm more wheel rate for the same engine input rpm, hence more top end. But remember, one can do about 10% of sprocketing. You are also only shifting the power band, not increasing the torque.Hope i made you understood and not confused [emoji2]

Re: Pulsar 200 NS Owners Review and Experiences

Yes you made the understood.thanks a lot.i thought 200had short gears,but this clears my confusion.
So I think if sprocketing is done then it impacts speed.but I also think it will impact the speedometer and will show more errors right ?

Re: Pulsar 200 NS Owners Review and Experiences

See speedometer is measured nowadays not from front wheel. Same goes for tacho,odo,etc. So doing sprocket swap will reflect. Any changes to either sprocket will affect the speedo and odometer. So you can see some doing 166kph in ns (in you tube)when measured through gps comes close to 150kph which might seem impossible, but all this is because of this +1 on front or -2 on rear tweak.

Re: Pulsar 200 NS Owners Review and Experiences

that's not true, each & every commuter or made for India bikes have speedometer connected to front wheels.
The new generation bikes which have digital consoles also have the same arrangements i. e. connected to front wheel but unlike the analog speedometer which have mechanical cable connected to speedometer to rotate the analog meter. digital consoles have magnetic circuit to sense speed connected to front wheel.

Re: Pulsar 200 NS Owners Review and Experiences

Thanks a lot brother.Even i was shocked to see such a speed for NS,most of them from Indonasia where they get to around 155-160.THis clears my confusion

Re: Pulsar 200 NS Owners Review and Experiences

Thanks for the update, from magazines and reports of motorbikes i considered that.

Re: Pulsar 200 NS Owners Review and Experiences

Yeah, you can do it on your AS as well, if you tweak your sprocket, but you have to compromise on low end though [emoji3]

Re: Pulsar 200 NS Owners Review and Experiences

Undergeared my ns by using d200 sprocket kit ..
And i touch upto 140 in 6 th gear at redline ..
Low end has improved a bit and picks up quickly under load compared to stock ..
I was just experimenting with it and quite happy with setup ..

Re: Pulsar 200 NS Owners Review and Experiences

Under geared ?

Re: Pulsar 200 NS Owners Review and Experiences

Do you guys have an idea, what the "bulge" in the centre of the rear seat of the NS/AS do? Or whats the idea of having that bulge in the rear seat?

Re: Pulsar 200 NS Owners Review and Experiences

I've got two questions.
1) I've clocked just over 18,000 Kilometers on my Pulsar 200NS. The stock Eurogrip tyres don't inspire confidence anymore during cornering or in wet conditions. Looking for an upgrade. Any suggestions please? I've scrolled through 100s of pages on this forum. MRF, Pirelli, Michelin and then the sub models in them. Got confused!
Requirement: I use the bike for daily commuting to office(Bangalore traffice and potholes!) and occasional weekend highway rides(mostly once a month). What tyres would suit my needs? I'm expecting good grip on both dry and wet roads, good handling and comfort. Budget - Around 5K for a set of front and rear(don't mind spending a bit more on top if the price is justified). It would also help to know if anyone has a good experience with any dealers in Bangalore(I stay in Marathalli)
2) The seat hurts my bottom! Pillion comfort isn't that great either. I've been thinking from a long time to do something about it but haven't acted till now! I think I'm finally ready to get that sorted out. Any suggestions for that will be helpful as well

Re: Pulsar 200 NS Owners Review and Experiences


You mean EuroSlip, don't you?

Re: Pulsar 200 NS Owners Review and Experiences

For 5k go with mrf zapper Fy2 for front and revz s for rare it will cost u around 5.5k
For seat comfort add 1inch foam but it will increase ur saddle height

Re: Pulsar 200 NS Owners Review and Experiences

Yes under geared ..
