RIDE
AND HANDLING :
All
these bikes are good handlers, surefooted and exhibiting
good poise through the bends. It's just that as you go through
this pack, the bikes just keep getting better and better,
culminating in the country's sharpest handler and leanest
leaner. The YBX125 uses a single downtube frame with the
engine as a stressed member. She handles delightfully thanks
to her light weight and has excellent manoeuvrability, ideal
for city commuting. However the skinny 2.5x18 tyres limit
grip in the corners resulting in quite a few uneasy moments.
Her lack of high-speed stability is also disconcerting.
Ride quality is good though with a pillion on-board the
front becomes too light for comfort. Riding position is
conventional and very
comfortable without causing any strain on the back.
The GF125 boasts a rectangular section perimeter frame with
double downtubes that looks fabulous and work very well
too. The GF flows into corners willingly and without fuss.
However the riding position is far from ideal. The mismatched
riding position plays havoc and just doesn't let you do
anything right which is a crying shame for the bike holds
its line into corners exceedingly well, affords a decent
ride and with a suspension set-up which never bottoms
out, not even with a Adnan Sami-type pillion on board.
The twin downtube chassis of the Fiero is rigid without
any hint of flex, but that's as far as praises go. The riding
position isn't sporty in any respect and doesn't encourage
you to put it down through the corners. Ride quality when
solo is good though with a pillion the front end gets queerly
light and many a time aims for the sky more than the tarmac.
The
CBZ uses a single downtube frame with the engine as a stressed
member.Thanks to the huge 100/90 profile rear, grip through
corners is excellent though a set of fast left-rights does
throw up limitations of the chassis as far as rigidity and
turn-in are concerned. Riding position is sporty though
it can begin to get tiring on the arms and shoulders after
a while. Ride quality is of a high order, in fact the best
of the lot.
The
Pulsar is the bike to go corner hunting on. The riding position
is perfect, the weight balance has been perfectly optimised
and the suspension componentry has been well sorted out
to result in an excellent handling bike in every respect.
The twin downtube frame is flex-free and in terms of flickability,
there just is no competition. Rake angles have been optimised
for quick turn-in while the MRF Nylogrips give you the confidence
to genuinely go peg scrapping. Ride quality is also good
though the rear tends to bottom out a bit with a pillion.
BRAKING :
Drum
brakes: so called because of the loud noise emitted as a
bike crashes into a wall you were hoping to avoid. Precisely
the reason why we advocate disc brakes, at least at the
front. Less noise pollution as a consequence of being able
to stop before the wall retards you.
Of the bikes on test, only the YBX125 and the Fiero sport
130mm drums at the front and rear while all the other bikes
sport disc-drum setups for optimum retardation capabilities.
The YBX125 performs very poorly in the retardation tests,
taking all of 3.7 seconds to come to halt from 60kmph, covering
28 metres in the process. The skinny 2.75x18 tyres do not
help matters either.
The Fiero performed slightly better than the YBX, taking
3.4 seconds and took26.7 metres to come to a halt from 60kmph.
Straight-line stability under braking is much better that
the YBX though. The CBZ employs a 240mm disc at the front
that results in vastly superior braking abilities, 21.5
metres and 2.7 seconds to come to a standstill. The GF125
uses a smaller 220mm disc up front but still returned better retardation figures, 18.6
metres and 2.3 seconds to rest. The best of the lot though
is the Pulsar, the 240mm frontdisc hauling the bike down
from 60kmph in 2.3 seconds covering a distance of just 17.4
metres in the process.
All
the disc brake-equipped bikes show tremendous poise under
braking without any tendency to step out of line. Feel through
the levers and control exercisable is of a high order with
the Pulsar's disc being the best of the lot, closely followed
by the GF.
Fuel Efficiency :
All the bikes on test here have been tuned to strike a balance
between efficiency and Performance.
As such none of these bikes will ever return 80kmpl not
even under ideal conditions but then none of them will murder
you at the pumps either. In terms of Fuel
Efficiency, the Fiero is the clear winner, thanks
to the digital ignition, CV carb and ideally matched gear
ratios that ensure that rpm is kept in the peak torque band
eliminating unnecessary gearshifts and over-revving. The
Fiero returned a best figure of 63kmpl while the worst figure
was 50kmpl. The GF125 was a pleasant surprise. In theory
a four-valve head should improve breathing while digital
ignition should result in an optimum spark, all leading
to a more efficient engine with cleaner emissions. Theory
works beautifully in the GF, at least in this test category.
She returned a best figure of 60kmpl while the worst figure
returned was 50kmpl. These figures put her right up in the
mileage stakes, made even more commendable by the impressive Performance figures.
The YBX125 came in third overall, a commendable Performance considering that the little 125cc Yam doesn't get whipped
by the bigger bikes at the test track either. She returned
a best figure of 58kmpl while the worst it dropped to was
49kmpl. You win some and lose some. In the case of the Pulsar
150 you win the race to the chequered flag but then her
thirst increases slightly. Even then a best figure of 55kmpl
and a worst figure of 42kmpl is mighty impressive what with
her ability to run rings around the other bikes here. The
CBZ didn't impress with her mileage figures, returning a
best figure of 53kmpl and a worst figure of 42kmpl, placing
her dead last in the mileage race. Tough on the wallet,
running the CBZ it is. |
