Author Topic: Performance for B400? (Read 9148 times)

MasterM3 · « **on:** March 07, 2006, 03:59:16 PM »

This is going to seem trivial to most, but does anyone have some data on the performance figures for a 91 B400? I only ask because this is my first bike and I don't really have any concept of how this bike compares to cars and other motorcycles. I have a pretty quick car and can guesstimate its performance in relation to other cars, but since this is my first bike, I don't really have any idea. it certainly feels faster then my car, but other factors lead me to think, I believe the bike to be faster then it is.

I was toying with a Infiniti G35 and would roughly guess that we were about similar in terms of acceleration. I believe this car can do 0-60 in 5.5 and the quarter mile in 14.8 seconds.

Is it safe to say that the b400 is about similar?

Comparing your new little B4 to other bikes will not be good for your soul.

IIRC, she puts out about 54 at the crank. Prolly <50 at the wheel. With a decent launch, <6 sec 0-60 should be doable. Search around this forum. Theif400 and gsxr400racer (or whatever) have both had their (pretty highly modded ) 400s at the strip. I don't remember their times off the top of my head.

Here's a good page with some stats.

ive seen that page. i just have trouble believing the bandit can do a sub 13 sec 1/4 run and 0-60 in under 4 seconds. :( i really wish it could tho

That 1/4 mile time is corrected to 59 degrees F @ sea level.
Mine does the 1/4 in 13.5 and 96 mph
Yours is going to be slower as your bike only has 32mm carbs

You can't really compare bike perf/mods like you would car perf/mods
the rider is 70% or more of what makes the bike go. The stock bike can
almost keep up with a lot but its never gonna really kick ass, it'll just
prove most of the riders around you aren't that good...

...unless you start buying kits & cams & all from gsxr400racer

e36 or e46 M3? Either way, the launch is up to the rider skills (or newbieness), and the M3 should kick the bikes ass above 60mph. Sub 14s quarters are not out of the question... I've embarassed a few hondas/acuras that way before.

0-60 can be rediculous, even with a newbie rider (I've done it in a few car lengths on a 65mph freeway before, from stopped on the side of the road).

BTW, if you say it's an e30, I'm jealous and you MUST post pics.

not an e30, but ain't complaining

0-60mph in a few car lengths? Like 45 feet?

V=D/t gives me a 0-60 time of 0.511 seconds for your bike! Holy crap! That's faster than 1000 horse top fuel bike dragsters

Maybe it just seemed that quick given the circumstances? Hehe.

Here's a clipping from a Cycle World test of the 91 bandit. They measured 0-60 in 4.1 secs. Quarter mile in 12.99 @ 101mph. Those numbers confirm my seat of the pants comparison to my car as well. The bike is a little quicker from 0 to 60, after which, my car would just walk my little bike.

how accurate are those times you posted? i swear if those numbers are correct, I should have been walking all over the g35.

Um, I dunno, I wasn't there in '90 when they did the testing.

I would assume that a moto magazine would have their testing procedure pretty ironed out tho.

Yeah, you should have. IF he was stock. And IF you were a trained motorcycle journalist, on a prepped drag strip, with a hand-picked, well-tuned, fresh factory bike, shifted optimally, got the track for a few hours to practice...etc.

Point being is that there are too many variables involved to determine why you were about even with the G35. Driver skill being biggest usually. No offense intended...it's my first motorcycle in 30 years that doesn't have knobby tires!

These high-revving fours don't have a lot of torque. Maybe try keeping the revs up next time?

I can only base my seat of the pants feeling of my bike's performance (haven't taken it to the track...yet) against my experience driving my car down the strip. I've got hard numbers on my car's performance, (and raced a couple G35s) and can tell you that my 91 400 feels quicker from a dig to around 50/60, but doesn't pull nearly as hard to 100 as my 12.2 @ 115 1/4 mile car. So, those magazine numbers seem about right.

You can always take it to the track & let us know your numbers...

1/4 12.640
mph 104.15 this is my time at the drag strip

Theifs time 13.56 @ 96 mph

Just as reference.

Having done a little drag racing in both 4 wheels & 2, I can say it's a helluva lot easier to get a good launch out of a car! I've never had to worry about flipping a car on it's lid from leaving the line hot.

Yeah, me neither. Well, at least since I installed the wheelie bars.

Thats why i got a 2 step rev limiter and a wheel bar for mine, to run comsistant

Jay you should add that your race bike is about 100 lbs lighter than a road going bandit plus i weigh 250 lmao that don't help either
