I AM IMPRESSED!!!

139 kg and 31 hp. That is incredible. Honda took 50 more cc and 30 more kg to do that. Let me rub that in

Sell it globally. This is record setting recovery pace.

That ugly karizma refresh shown earlier makes this launch merrier.

It looks great too. Why can't you guys to each of Honda cbr 300 markets with this and start eating their pie.

now i need to search, what is a geodesic frame.

quite true.

depends on the amount of "combi" factor in combi brakes.

The geodesics intersect to form triangular elements that have local triangular rigidity and also distribute the stress across the structure. Geodesic designs can be used to form any curved, enclosed space.Such structures may be composed of struts of uniform length while having faces other than triangles such as pentagons or squares, or these faces may be subdivided by struts of other than the basic length.

Now its time to see what Bajaj going unveil to beat Hero.

From what I gather from your above message, I guess you understood wrong. Stress member implies that the weight of the engine plays a pivotal role in further distributing weight of body and rider along the chassis and which further effects the center of gravity.
In typical cases like normal bikes, the engine is simply cradled by the frame. It has bolts which mounts it to the frame. Addition or deletion of the engine to the frame hardly makes any difference in the tensile strength or in the rigidity of the frame.
However when engine is used as a stress member, it becomes part of the frame. Without the engine, the frame would become less rigid. In other words, it is solidly mounted. Unlike normal frames. Because of such mounting, you have lesser engine vibes even at higher rpms.
And the engine however does not take the entire load. The word stress does not mean literally that the engine is stressed. It implies that the weight of the engine helps in stressing the frame without which the frame becomes less rigid. That's what I've learnt.

^^ i partly agree and partly disagree.

yes, using engine as a stressed member can lower the center of gravity.

but if the rest of frame is properly designed, it increases the rigidity.

while too much flex is bad, too little lateral flex is also not good, specially while cornering.

1.5 lakh is beyond my budget

.

Btw, combined brakes without wheel speed sensors?! Is it safe? I think a combined braking system without abs on a quarter litre bike is a stupid and dangerous idea!

Nope but I loved mechanics. Well that is actually a part of mathematics and it is mostly about the coordinates.

Explains nicely about the Geodesic frame..:

Erik Buell

Quote from the article link:Buell selected the expensive but effective method of using chrome-moly alloy steel tubing to build a perimeter frame with triangulated sections. Buell calls it a “geodesic perimeter frame.” In the best modern fashion, the engine serves as a stressed member of the frame. The result is an exceptionally light and stiff frame, which improves handling and control. A bike that handles precisely and delivers exceptional control is more fun to ride.

Combi brakes are there whether you choose ABS or not.

Any option if we don't want the combined braking. Like if I don't want to opt for it..

What's your problem with CBS?

It will kind of feel awkward and I am fine with the way I am braking

Quote from the article link:Buell

So going by this we can easily assume that this is going to be great handler?!!(maybe it comes out to be the best handling bike beating the R15 v2)
It will be good for a bike in India as it's light weight will make it easy to maneuver within the city traffic & the light but still rigid frame with pirelli sports demon rubber combined with slightly horizontal rear monoshock will make it stable at high speeds:thumbup:

Oh man, now just one thing we want is a engine which would have a good low end as well as high end power without crazy vibrations

re: Hero HX250r revealed, with 31ps Liquid Cooled Engine: xBhp News

Hx250r seems to be the only bike in India next to the bsa-bond gt50 to have a cantilever type rear monoshock. This should improve handling greatly.

Shouldn't. You'd only be shedding speed faster.

There are various versions of CBS, lets see how HMC has implemented it. Combined braking system - Wikipedia, the free encyclopedia

then you have to modify it and de-link the front and rear brakes.

btw, isn't combi braking patented by honda..?
