Marlboro Yamaha Sepang Setup

MotoGP 2002 - Round 14 - Sepang - Yamaha - Set up report
October 10th, 2002

Because of its hairpins, and numerous hard braking areas, a fast lap and any hope of making a pass at the Sepang circuit comes down to braking stability and the bike's turn-in characteristics. Two such areas include the two long straights and hairpins that make up the final sequence of the 5542m layout. The task is made a little easier for the suspension technicians with the track surface boasting a high level of grip and few bumps, but it is a venue that also offers challenging high-speed sweepers - the first, diving down deep into a hollow before climbing back out the other side for a 90 degree righthander. This has a tendency to load up the front of the bike to the extreme. The other is a blind lefthander that disappears over an undulating crest, which ensures that keeping the back-end in line will be more challenging than it appears on screen.

It means that the chassis' balance will be compromised, to a degree, to ensure that the key areas of concern are catered for - such as the braking stability and chassis agility. To help cater for both, the centre of gravity will be moved slightly to offer better feel from the front-end as the rider dives into the turn - increasing confidence and therefore the rider's speed. While, the suspension balance will offer braking stability by rising the front and lowering the rear. The front fork springs will be slightly firmer, achieved with a higher spring rate, with the bike's attitude controlled by the spring preload. As for the rear shock, it will also carry a high spring rate, but it will still be plush enough to offer the feel needed to get the power down hard and predictably in conditions that can melt a rear tyre in a matter of laps.

Both Checa and Biaggi will head to Malaysia with chassis combination used at the Motegi MotoGP the week before. The Spaniard has opted for two of the latest specification, while Biaggi will fight for his number two spot in the championship with one new unit and his preferred chassis. The latter is identical; chassis wise, to the two YZR-M1s the Gauloises Yamaha Tech 3 riders Olivier Jacque and Shinya Nakano will use to make their four-stroke debuts. And, time permitting, Checa and Biaggi may also test the latest rear swingarm offering initially pencilled in to make its debut in Japan.

Being four-stroke mounted will prove to be a big advantage for the Tech 3 pair with the high humidity the biggest concern for the 500s - typical in this region during the month of October. This circuit requires a good, consistent and strong low to midrange power delivery, but the high humidity can actually deprive the two-strokes of around five percent of their full horsepower potential. The high air temperatures, which can cause the engine to run around 10-degrees Celsius hotter than normal, amplify this again robbing the bike of power.

Is it weird in here, or is it just me?

Keen as

Would love to see the qual results when you have them....

Here you go this is the only thing you need to worry about - these might help you get your start timing right from the comfort of your desk. Just be careful you don't dump the clutch too hard and fall off the back of your chair....

GO GO GO!!!!!

First practice

9pm!!!! So are you going up tonight or not until tomorrow morning?

Got feel sorry for Pitty, talk about thrown in the deep end he's never even been to Sepang before and this is the first time he's even tossed a leg over that funny looking green monster.

True story: In the early days he used to race proddie bikes as his school sport!!! His mechanic was actually his Phys Ed school teacher
