I agree. These were my thoughts too. To add to that, a LC system means you need to take extra care for these components against mud, water etc.

the pics are not that good as always, maybe of the bigger watermarks of XBHP was looking in between to see the bike

@MG: Thanks for the clarifications.. But, the point in that interview where you said that M&M will not give a test drive unless you put down booking amount is ABSOLUTELY RIDICULOUS..

I mean, Ninja is given for a test ride in an ORGANIZED MANNER once a month here in Chennai to people who inquire about it.. But, this concept is gonna turn down many people just for it sheer ludicrousness..

Guys, pl remember that its a 300cc SINGLE.. The P220 is a single cylinder air cooled engine.. Do you guys have ANY IDEA about the AMOUNT OF HEAT the 220's engine generates in CITY TRAFFIC..? Trust me, i've been enduring it for 14k kms for over a year now.. I don't think customers would appreciate such a BAKING EFFECT of one's family jewels on a near 2L bike in city traffic..

That is the reason the bike is equipped with LC.. I accept maintenance will be more, but then so will CONSISTENT performance..

Cheers..

It's the electricals testing process happens right after you turn the key to ignition. Same way rest of the bikes in india with digital speedo go up to 188

even if its the electricals testing process........i think it'll go 200+kmph atleast...as its not a complete seven segment display(for hundreth's digit)
its a six seg display(used for cost cutting measures)and a company like mahindra wont waste money for that.......if it was not supposed to cross 200kmph on speedo.......then they would have easily used a 2 seg display as they are used in 150 cc bike ........to display "1"......

^^^ come on dude
this bike will not be able to cross 160-165 at max..

lets wait and see its on road performance

How would us noobs have any idea about the amount of heat generated by IC engines? Of course not.

I suppose (based on your kind words) a 300cc single generates more heat than the Ducati 796 L-twin which is air-cooled, by the way.

There is no way this bike is going to do 160 kph. After 130 odd kph on the speedo, you are going to have to tuck in to get any further. I would love to be wrong.

in indian conditions over heating is a factor. who told you only p220 overheats. in heavy traffic even my r15 heats up considerably. but it never loses performance due to heating up. its an arguable topic. lets drop it.
about test ride. no one gave the r15 for a test ride before i bought it. but the brand name yamaha was reassuring enough to take the risk of buying it with out a test ride. but mahindra should not forget that this is their first product and they should know how to handle customers instead of acting arrogantly.

i agree. the bike redlines at a mere 8500rpm. if such a low revving bike is able to produce 165+ then it should be having incredible acceleration,which i doubt.any way the fact that it has 6 gears is sort of reassuring ,to an extent.

As I read somewhere that Air Cooled Engines are suitable in India than Liquid cooled.
Air Cooled system works even if the bike is standstill,whereas the Liquid Cooled System works when Bike is in motion.

That depends more on the actual stroke dimension than the ratio! Any 300cc single cyl. engine would rev only so much.

About the electrical sensor, what is so different about it? Same as on countless other indian bikes, right? And why do they need a blue LED there? Seems gimmicky.

C'mon they are reving only upto to 17.34 mps speed of piston while 20 mps can be achieved with larger ports and lightweight piston. Then only twin end cans can be assumed to be useful. Else second can is just dead weight.

**Samarth 619** · 10-03-2010, 04:34 PM

100/80 – 17″ (Front) 150/60 -17″ (Rear) mm
1450mm Wheelbase

I think the tyre choice is very wisely done by Mahindra! They took my earlier advice seriously. That's great!

But why such large wheelbase...? This will hamper turning most probably...
Also, I can't understand the design and targeting of this kind of machine...?!

About Top Speed as speedo has triple digits with "2" possible as the first digit:-> Guys, it might not be so as this component might be from another bike.
Or maybe its in a different state of tune, than earlier planned.

BTW, I'm reminded of how Karizma indicated 200 as max speed, and what I found on riding it fast to verify this..

With forged pistons and all, yes it's possible. But then, this I assume is Mahindra's first attempt at making a motorcycle engine. BTW, have you calculated the rpm at 20 mps?

About the silencer, I guess its 1 per exhaust valve.

At 20 mps, its 9803. Considering this, 10k seems to be easily achievable. However, for street reliability, mahindra wont take risk. I think this engine has got good potential to be boosted. Better to wait and watch for detailed specs. Right now, i am working on my RTR to touch 12k RPM.

**Old Fox** · 10-03-2010, 10:19 PM

Lots of apparent contradictions in the engine design if the given specs are anything to go by.

#1 Over-square dimensions are favored for higher 'red-line' rpm's. This one gets limited at a relatively tame 8500.

#2 Four-valve head favored for freer breathing which again indicates that higher peak rpm's are targeted whereas it is not so.

#3 Peak torque claimed at 7000 rpm. Not low enough to justify the design aim of the engine to be a low-end performer.

#4 Piston speeds < 18 m/sec. Again pointing towards a low state of tune while the decided over-square points towards a targeted high strung design.

I wonder if such contradictions point towards design issues with the engine if it were to be used at its full potential. Its like the designers started with say a targeted 30 PS but encountered problems, either thermal or with machine dynamics (I suspect the latter as they are the most difficult to pin-point and eliminate), and so deliberately de-tuned it for a lower bhp output and a lower peak rpm. Just guessing but the history of engine development is littered with such instances.
