Re: TVS Apache RTR 200 4V

Can anyone explain how does Ram Air Intake works in apache,

In apache its not even connected to air intake and in carburetor is it possible, even though its possible i dont think it will improve any efficiency or power.

Whats the use if its just directing air towards spark plug.

Re: TVS Apache RTR 200 4V

My bad,
Apache just has RAM Air engine cooling Not RAM air intake,

so basically 5 speed will have more torque in every gear compared to 6 speed keeping 18.1NM @ 7000rpm constant which will result in better acceleration at low and mid range .
Now if they want to take advantage of the 6th gear, then they have to increase the torque by making it a little more high revving engine which will result in little more max torque at little more higher rpm. The catch is it will help you in the top end and not at low/mid range where the city riding comes into play.
This is a big link where everything accounts, the max rpm at which max torque achieved, the gear ratio and no. of speeds and all these things will represent in the Curve.

hi dinesh.
this is not how the torque is given by an engine. the torque is not divided between gears. a torque curve is the relationship between the ENGINE speed and torque produced.
gear ratios are basically a ratio between engine rpm and final drive rpm. the addition of a 6th gear would successively reduce the ratio, thus achieving a higher rpm at the wheel compared to an earlier gear at the same engine rpm.
the torque available in any gear at a particular rpm will always remain constant.

Touring bikes generally have a 6th gear to enable higher speeds at lower rpms, where torque requirement (acceleration requirement) is relatively lesser. this also enables cooler running and fuel saving.
a bike mainly for city runs doesn't always need a 6th gear, because, to fit a 6th gear, the gear ratios of the other gears have to be adjusted. secondly, a 6th gear,as explained earlier, can't convert that torque into usable acceleration because of it's smaller size, it causes knocking in the engine.
The correct reason for not having a 6th gear is probably the one explained by Divyesh.

Agreed on your point. Thats what i have been explaining. But when i said torque divided into 5 speed that doesnt mean divided equally, what i mean is adding a sixth gear for this engine would not give the exact result which it gives now.
Anyhow i think TVS has got it right for the purpose what it being made for.

i would disagree with you here too.
the 200 has a very linear torque curve which starts quite low on the rpm band. having a 6th gear plonked on top of the current set up would be extremely beneficial for tourers because it would significantly reduce fuel consumption. there would be almost no acceleration capability, but consumption will see a significant drop. as a result, makers generally try to fiddle around with the gear ratios of the other 5 gears to get some more power in the 6th. this is taking time i assume, getting the ratio of the ratios right...
maybe TVS should take its time to ensure proper development of this new gear case.

This is not a tourer bike. this is a city bike and hence 5 speed makes sense for this type of engine configuration.
Adding 6th gear wont do any harm to the bike, but low/mid range needs a little compensation to benefit the 6th gear.
For tourer , yes 6th gear would be more beneficial, but for RTR 200 is concerned the purposeof this bike is totally the opposite.

and finally we agree.

i did not say this bike needs a 6th gear. i replied only due to the torque-gear ratio thing...

Bhai....we Indians can tour on bajaj scooter also. There is nothing like true tourer 2 wheeler available in India.
Every 2 wheeler can be a good tourer if ridden in its limits and if rider have patience to ride in its limit.

Re: TVS Apache RTR 200 4V

TVS actually tried to add 6th gear, but failed to do so under a time limit. Their actual motive was to make RTR200 best in the class, but their engineers faced time limitations + hard work in freshly redesigning the RTR180 engine.

So they put it under the tweaked 5 speed gearbox. This is an insider info.

1. Wrong info. Trust me on that.
2. The 200's engine is not an all new engine. Its a heavily modifed engine of the 180 with counter balancer and 4V head.
3. Their main goal was to keep the costs as low as possible and having lesser moving parts.

No, it costed me 1,04,980/- here in Ahmedabad, All colors were ready for delivery on the same day except matt yellow. I didn't paid any premium or i didn't awaited so long for the bike

i got it after only two hours of booking.

Cool .. Here in Mumbai it's 1.10 lacs and still grappling for red color. They are pushing white/ grey/ black and that too few dealers asking for 5 k premium.
