Hero
Honda has lately upped the ante of the two wheeler industry
at both ends, upper end as well as lower end. At the lower
(100cc) end it set the cat among the pigeons by launching
the no-frills CD Dawn at a price of Rs.31,000/- ex-showroom
(Rs.33,800/- on road) Pune, which made it the cheapest bike
in this largest selling class in the country. At the upper
end it launched the Karizma, at an on-road Pune price of
Rs.86,367/-. While the CD Dawn retains the same engine,
mechanicals and cycle parts of its higher priced siblings
in the 100cc class, the KARIZMA breaks new ground and for
the first time, breaks the 200cc barrier in the four-stroke,
single-pot, Indo-Jap genre. While the Specifications
and Performance of the HH 100cc
class is too well known to bear further mention here, the
Karizma is an altogether different cup of tea, which is
a stunning 223cc single, spewing out 17 bhp at 7000 rpm,
which pushes the bike at a torque of 18.35 Nm at 6000 rpm.
This is the Hero Honda with a difference. What is this difference?
The difference is that unlike all other HH bikes, which
have short-stroke engines, this one has a Long-Stroke engine.
All the earlier HH bikes have the same stroke of 49.5 mm,
with only the bore varying (increasing), being 50.0 mm for
Splendor, 58.5 mm for Ambition and 63.5 mm for CBZ. The
Karizma on the other hand has a stroke of 66.2 mm, which
is more than its bore of 65.5 mm. This not only gives it
excellent Low End Torque (LET), but also allows it to produce
its max. 17 bhp at 7000 rpm, while all the other HH bikes
named above produce their max. bhp at 8000 rpm. Thus the
Karizmas Engine Life Factor (ELF) is almost 1.6 which
is better than excellent, and more than most other bikes
in the country today. With the long-stroke giving it excellent
LET, and a low rated rpm giving it longevity, one is assured
of relaxed riding pleasure for many years. It is a medically
proven fact that relaxed riding increases the longevity
of rider as well.
In
addition to the fact of the Karizma being the most powerful
current Indo-Jap bike, is another important fact, especially
for the enthu brigade and the modification maniacs, which
is, MAG WHEELS. As bikeguru@cybersteering.com I everyday
get Emails from people wanting to change from spoked-wheels
to mag-wheels. Now here is a bike that comes with mag-wheels,
FACTORY FITTED. End of quest. The mag wheels on my test
bike are black with five straight webs each. Tyre sizes
are 2.75 x 18 front and 100/90 x 18 rear.
Apart
from breaking the 200cc pot size barrier, the Karizma breaks
another barrier. It breaks the four-second barrier for zero
to sixty kph, claiming to do it in less than FOUR seconds,
3.8 seconds to be precise. This is one claim I had to check
out immediately and in spite of the rains having begun,
I got a chance on Sunday 15th June 03, on an excellent dry
tarmac surface with no slope and no traffic. The Karizma
was ridden by Amol Phansalkar (age 27 ; weight 67 kg ; height
174cm). We did ten runs and recorded a minimum timing of
4.3 seconds four times, with the other six timings being
between 4.3 and 4.7 seconds. So I take 4.3 seconds as our
best and most consistent timing. Yet I say the Karizma easily
does zero to sixty, in 3.8 seconds (as claimed by HH), or
maybe even less. How come?
