Posted on 06/06/2005 8:12:11 AM PDT by Responsibility1st
Rico Lamar Porter doesn't have a license to drive, but apparently he thought he had a license to fly Wednesday afternoon.
Porter, 27, of 25 Dyer Drive, Hickory, was arrested after leading state police on an eight-mile, 170-mph chase on traffic-congested Interstate 70.
That's no misprint. Commonly referred to as a sport bike or "crotch rocket," an aerodynamic motorcycle like the one Porter was operating is capable of speeds of around 200 mph.
Trooper Martin Gonglik was running radar about 4:20 p.m. near the Dunningsville exit of the highway when he clocked Porter going 120 mph.
Gonglik activated the lights and siren on his police car and attempted to stop Porter, but the motorcylist instead took off. With the trooper in his marked police cruiser in pursuit, Porter weaved in and out of eastbound traffic.
At times, he drove on the berm to get around vehicles. And not surprisingly, Porter didn't use his turn signal during lane changes.
Porter got off the highway at the Centerville exit and momentarily lost control of his slick speedster. Gonglik swerved to avoid a collision, hitting a guard rail. Porter again tried to flee, going south on Route 481, but ended up hitting the side of the police cruiser. Porter, who was wearing a helmet, was slightly injured and taken to Washington Hospital for treatment.
District Judge Jay Weller initially thought police had made a mistake when he read the criminal complaint filed against Porter.
"When I asked about going 170 mph, he just nodded his head," Weller said of Porter. "He was very forthright about everything. He said he just got the bike two weeks ago and hadn't even made the first payment."
Porter told Weller that his bike-riding days were over.
"He said it was a good thing that the trooper caught him because he probably would have killed himself," Weller said. "He was trying to catch up with some friends. He wondered why he caught up with them so quickly, but they had seen the trooper and slowed down."
Porter was arraigned before Weller on charges of reckless endangerment, fleeing and eluding police, driving with a suspended license, having no registration, having no insurance, driving off the road, not using his turn signal, failing to drive at a safe speed, speeding, careless driving, reckless driving and not having the vehicle inspected. He was placed in Washington County Jail on $2,500 bond.
A preliminary hearing is set for Tuesday before District Judge Curtis Thompson.
It would have to be a dynamometer with a wind tunnel attached, since they only measure force (or horsepower).
Uh, you'd be surprised (speaking hypothetically)
I don't know this for sure, but I may know the guy who submitted that video. He's submitted videos to a number of web sites.
Speedometers are nortoriously "optomistic," although if this is an earlier 'Busa that's had just a bit of work done, then 200MPH+ is quite possible.
They guy is nuts...
I think "this guy" passed me just a few miles west of Needles, CA about 9 months ago. I was doing 80 and he zipped by me like I was standing still.
Psst. 205 squared divided by 170 squared = 1.45
Secondly, its not a matter of KE but rather power vs drag.
cool! I want one for my 56 year-old frame!
Before the manufacturers put limiters on them, the Kawasaki and Suzuki were both clocked by motorcycle magazines on test tracks at over 190MPH, and IIRC, one hit 197MPH.
However, the EU threatened to slap a 100% tarrif on the bikes if they could exceed (I believe) 300KPH, so they added limiters to keep the speed "down to" about 180 - 185 MPH.
Ring ding ding ding ping
Oops! Must've Oh well, it amounts to probably another 67 horsepower (45 percent of 150). Not likely without a turbo or nitrous.
Yeah 77 percent more would've been 226 MPH.
square root of ((170x170)x 1.77)= 226
I looked at the video-- he appeared to be in sixth gear at about 11,100 rpm. I think we could figure out his real speed based on gear ratios, provided of course his sprockets and gearing are stock.
TYVM for the clarification
I've got a Ducati 900SS, and I was clocked at 125MPH on the front straight a Heartland Park raceway in Topeka KS. That was as fast as I wanted to go, because it's the 1/4 mile track used for drag racing, and then there was a sharp right, then an immediate sharp left turn at the end! You'll see it in this photo at the left, about 2/3 of the way down the straight.
The worst part of the track (the first time I rode it) can be seen on the right side... Notice that it seems to be straight, then there's a litle "chicane" (a jog, to help keep the speed down), then another short straight... What you can't see in this photo is that both strights are going slightly uphill, while the chicane is flat and level. That means you can't see the chicane until your're practicly on top of it... My first time there, I managed to do a bit of "dirt tracking," going straight, missing the chicane altogether! It was a serious "pucker factor" moment!
the last time I was there, Heartland Park didn't seem like a terribly safe track for motorcycles... The track surface was pretty bad (there were different surfaces at some of the points where the bike was leaned over, and traction would change), and there was limited "run-off" space, especially at the top of the photo, where the road course merges back with the 1/4 mile drag course, where if you ran wide, you would wind up hitting concrete barriers! It's been a while since any major races or riding schools have run there because of those conditions.
All of this before he made his first payment no less. Welcome to the world of your average Boy Racer crotch rocket rider. This is why I'd rather ride with the RUBs than the Rocketeers. At least the RUBs know they aren't Superman and won't inadvertantly take you out in their quest to become another grease spot on the pavement.
I don't believe the mechanical speedo on my bike, having calibrated it by stopwatch at both 60 and 120MPH. I DO believe my electronic tach, and the readout from my GPS.
It's people like you that killed Tinkerbell. I've seen a new bike that was less than 4 hours out of the crate at the dealer's that turned in an honest 188 mph, as measured with triple stopwatches over a 2-mile stretch.
It then went home where the owner began the upgrades intended to see 200, in hopes of eventually hitting his goal of 222.
drag = Cd x R x V(squared)/2 x A
Cd = coeff. of drag
R = density
V = velocity
A = area
??? Absolutely it's a matter of power vs. drag, and as you can see from the drag equation (second one), the power required to equal the drag at any given speed is proportional to the square of the velocity.
Believe it. Your average Suzuki Hayabusa will do this right off the showroom floor using pump gas. Many more models will do the same with a simple swap of the ECU IC. The dealer will hand you the keys without any skill test, sanity check or even a license check. All you need is enough cash for a down payment. You too can be Superman!
Don't forget your helmet. You'll need at least one body part intact for identification purposes. Dental records work the best . . .
Put another way, the kinetic energy is not much of a factor-- if the Hayabusa weighed 2,000 pounds, the horsepower requirement would be the same because the frontal form factor would still be the same, so the top speed would be-- the same! The kinetic energy at the same top speed would be much higher (also a function of the square of the velocity), but that only means the bike would take longer to achieve the speed. (Assuming the tires would take the extra weight, discounting the additional friction, etc.)
Yeah, but what if one tooth is at mile marker 185, another at 186, 3 more 1/4 mile east of there, etc.
The bike was probably heavily modified.
"First of all top speed for a Hayabusa right now is 183MPH"
If and only if you haven't replaced the speed limiter chip.
I went to Bonneville in 1954, in the very early days of Speed Week. There were a number of guys there with stripped Harley bikes, big engines of course. They ran stretched flat on the bike, chin on the handlebars and feet over the rear fenders, no helmets as I recall, hitting around 140-50 across the salt (which was like extremely coarse sandpaper). I wonder how many of them are still with us today.
"Also would like to add that I want to know what the trooper was driving that he could keep up with him at 170MPH...."
No kidding. The BS meter is pegging on this article.
They forgot littering.
If my memory serves me correctly, back in the early 70's following the unveiling of the Kawasaki 900 monster bike of it's time, federal legislation was introduced to limit horsepower-to-weight ratio on all motorcycles. Luckily the AMA & every single manufacturer was all over it and beat the proposed legislation.
Now moving forward to our time of WoT, WoD, no-knock raids, helmet law changes nationwide, motorcycling enthusiam, TV shows, massive weeklong bikefests, etc. etc. etc., are we in for another round of restrictive laws aimed at the 200+ mph crowd?
The only other consideration that is an accepted norm is that cage drivers have little to fear from a 500lb motorcycle and driver. But the hazmat scrape and removal teams are staying busy cleaning flesh, blood and fuel spills after a high speed crotch rocket squish. At triple digit speeds the only thing a helmet does is crack like an egg and retain DNA samples.
R1 doing 180 in traffic at night............
You would also have to account for the increasing tire size due to the additional speed.
Yup. My 1986 500 interceptor would go 120mph.
Yeah, slightly-- the z-rated street tires are rated for "over 149 MPH" but 220? Maybe some race tires.
Here's the URL for that turbo-Hayabusa video and many more-- the Hayabusa "night" video is INSANE
Correction make that the "Hi_Speed_Pass" video
That just killed about an hour of time here at work.
Yeah, and it's really not unusual for the insurance on a squid bike to be more costly than the payment. Deservedly so I might add. Then again, I'm probably biased in my dislike for them.
Oh yeah, I buy that. "Gee, occifer, if he'd only been wearing a helmet when he centerpunched that concrete overpass support, he would be ok today -instead of just a big stain coating it."
Lots of bone stock bikes will pass 170. Currently, the Jap manufactures are voluntarily putting 300kph electronic governors on their bikes. Defeating the gov is the first mod a lot of these guys do now.
120 is easy to hit. I've hit 120 on my Sportster.
Perhaps they'll bring back the Saint Joan of Claybrook (the DOT head under the Carter administration that brought us the "Backwards Bike") federally mandated 85mph speedometers!
Motorcycle world abuzz at biker's 205 mph ticket
MINNEAPOLIS, Minnesota (AP) -- People across the United States are shaking their heads over the kid ticketed for allegedly riding his motorcycle at 205 mph -- some out of disapproval, others because they doubt he went that fast.
Ever since a State Patrol pilot clocked Samuel Armstrong Tilley's 2002 Honda RC51 going a quarter-mile in 4.39 seconds on September 18, people in chat rooms, garages and biker bars from Sturgis, South Dakota, to Los Angeles have been buzzing about the alleged feat on Highway 61 near Wabasha.
State Patrol pilot Al Loney, a 27-year veteran, and his superiors stand by their report.
One guy even made the front page because he went over a cliff, and was severely injured with at least one broken leg that I can recall. His friends noticed that he did not come back the following Monday, and on Wednesday notified authorities he was missing. They finally found him a couple of days later when after going back and forth along Hwy 9, one of them happened to stop over a particularly narrow section where he noticed a long skid mark leading to a broken guardrail and thought he heard something when he called out the guys name. They wound up having to chopper the guy out -and only later found the bike.
About thirty feet straight up, lodged in a tree.
(C)San Jose Mercury News, about... '88 or so.
Who~~~~a. He had it on one wheel up to 130mph, that's nuts. At first I thought the speedo was in kmh but no, kmh is on the inside row of numbers.
'Backwards bike' Haven't heard of that boondoggle in years.
When I'd first read about the contraption in Cycle magazine (remember them?) I thought to myself, "Not even the government could be that stupid." Turns out I was wrong. They really did build it. I read where one of the DOT testers ended up breaking a collarbone trying to ride it.
I'd actually found a picture of the thing on the internet a few years ago. It was cobbled up from remnants of an RD350 if memory serves. Alas, they seem to have disappeared. I've been looking . . .
I used to work with a guy in the Bay Area that was a motor cop who patrolled the Woodside area, and he had a lot of biker crash stories to tell. They usually featured the bike or the rider in a tree, and the other party up to 300 ft. away.
from your link:
Claim: The remains of a smoldering JATO-assisted Chevrolet Impala were found embedded in the side of a cliff in the Arizona desert.
Ive had this one up to 180
This was posted at Motorcycle Consumer News at the time, and is a pretty fair description of what most likely happened:
Actually this guy has been posting on sportbikes.net and he said that he was riding a Honda RC51 with an aftermarket muffler, otherwise it's stock. That bike is by no stretch of the imagination capable of 200mph. Apparently the cop was in a plane using a stopwatch and was timing 2 bikes going different speeds with 2 stopwatches at the same time. He was timing them from hash mark to hash mark a 1/4 mile apart. Apparently the cops were patroling the area they knew a bike ride was occuring on.
