Mr Ferrari.. With all due respect.

You never know how a person rides, I ride in those places, that if I take you there, you will end up having God knows how many bruises and you will end up coming after atleast 30mins after i have reached the destination.

Just a couple of days back I was riding near New Delhi railway Station and ZMA's clutch got heated up!


Where R15 Survived Very Well..

But comparing with Liquid Cooled to Oil Cooled, LC is way Better and Efficient!

I did a marathon ride of nearly 22 hours back in 2008 from Bikaner to Ahmedabad( yes the distance is hardly 750 kays but half the roads were under construction) with a truckload of luggage on my Zma and given my size n weight, mann, at the end of the ride I gave in but the zma didnt! That ride had the worse of potholes as the entire highway was opened up. which brings to focus, the seat.. perfect for me..and opinions differ. I guess you are bigger size than me

While the ENKEIs may be heavier than say, the r15's alloys, they are incredibly durable and of superb quality. In the long run they hold their value well, as long as you're not a racetrack freak who's looking to shave off the last gram from the bike.

Not at all, if setup properly. On the cbz, we installed the zma enkeis and changed the front fork leg so that we could use the zma's 276mm disc. Kept the stock cbz master cylinder and caliper. Used the nissin pads which cost 1800 then. The braking was a revelation, naturally, the cbz's much lower weight is a factor, but the braking was miles ahead of my rtr, which even now after running the factory fit pads and disc for over 11k kms, still needs only one finger, and two for extreme braking situations. I have never used a disc brake with as much stopping power and feedback as the 276mm on the cbz on any indian bike. r15, haven't tried yet, but it's atleast twice as good as the rtr.

Yes, TPFC does only squirt additional fuel when you snap the throttle open suddenly, it works like the perfume sprays, you know, the ones without gas in them.

However, cooling effect, if any, would be negligible due to the fact that it only works under sudden throttle opening. An example of real piston cooling would be the 7th ports in the rd350, famously know as torque induction when clubbed with the reed valves, which actually keep spraying additional fuel on the piston crown, thus aiding cooling.

Vishu, taking decision just by looks on paper is not a wise idea. Why do not you wait till the bike is on road with proper road test. You can decide later.

Sandeep, I agree that R-15 is a great machine. I have been using R-15 for the past one month. You will not feel as comfortable with R-15 after using the ZMA.

What are you trying to say. And your post definitely does not sound respectful though you say "With all due respect"!

You use it on the CBZ and claim that it is powerful?! Even my Pulsar can brake with a single finger under most speeds. HH bikes generally have very mushy brakes! RTRs I have found, have superb brakes! Might be, your brakes need a check up!
