[Sketchy_Racer]

hey guys (and gals)

thanks to ivan and doug juggins i am going to be going to the trackday at manfield october 23rd (i think thats the right date) to ride thier mighty cbr, but im a little nervous 'cause iv only every raced buckets on a small track with top speed of 100kph... so is there any hints that people can give me about the bike...the track, corners, lines....
im so excited as i want to be a good as racer when i grow up and i believe all the information you can get is good and will add to riding skills.
cheers for any help

You learn from your mistakes as well as just hopping on the bike and riding.

The only advice I can give is beware because the CBR will take you buy surprise esp when you are used to dealing with buckets all the time.

Good luck and tell us how it goes.

Just be as smooth as possible and dont rev the bike past 18k. Keep the rev counter between 9pm and midnight for best performance and use the gears to keep it there. On the cibby round many tracks its all about throttle control rather than powering it up and hanging on the brakes.

[Sketchy_Racer]

awesome guys keep it coming, cheers

[MOTOXXX]

fold in your mirrors so you dont look behind you for riders.
just go out and have fun.

[Sketchy_Racer]

yea its all about the fun!!!!!!!!!!!!!!!! ;)

Keep the revs above 10,000 around a corner cause if you go any lower its harder to bulid up the momentum going out of the corner without shifting down a gear. Also max power is at 16000rpm so theres no need to go further, this will spare the motor some effort and make it last longer. And most important of all, don't lean over too far or let other bikes crash into you. It's rather expensive

The CBR makes a good race bike :niceone:

And also don't bother trying to keep up with zxr250c's.. it will just make you look silly.


:done:

Have fun mate, I hear cbr's are a little more prone to scraping pegs than zxr's due to the position being lower (eg zxr's you are on the edge of the tyre to do it :|), but I'll let a cbr rider explain it because I can't really...

Will be a nice stepup from an rg100 for sure!

Will be a nice stepup from an rg100 for sure!

Yep cause you definatly aint beating my RS mate

[Sketchy_Racer]

yea i know but ill try!!!!!!!!!!!!! muhahahahaha ha

It depends a lot on if you want to go racing or just wanna improve your riding skills. Ill work on the theory you wanna go racing.
1) get a map of manfeild and blow it up to A4 size.
When you get there either Bicycle -slowly round it or walk around the track. Take note of camber and possible lines to start exploring. especially see how heavilly cambered Higgins and the hairpin are.
2)remove mirrors and tape up speedo -Dont look back.Focus on YOUR riding not on anybody else.
3)Don't try to be a hero and prove you're a big man -sometimes you'll find backing off and riding a corner-or sequence of corners slower will give you a better understanding of how they work

4) line first speed second.--sorta a repeat of last suggestion but your focus should be on finding lines that work
5)--What I do --works for me sorta --Focus on getting 2 corners right--- The ones You KNOW you are stuffing up. both ends of the circuit. -the rest of the track I just circulate at a brisk -not fast pace -then change my focus to another 2 corners --I'l qualify that a little for manfeild in that from coke to the hairpin is a linked sequence of corners that you need to chip away at together ish
6) when you need Help --ask for it--I'd watch the guys who seem to be getting it right and ask their advice --or even ask if you can follow em to figure out lines.
7) HAVE FUN ---MOST IMPORTANT

The person I'd talk to about punting a 250 around manfeild is weazer --that lady had her lil bike fair flying

[Sketchy_Racer]

thanks for the help frosty,

yea i wanna get pretty serious, eg i want to 'race' not just improve my skills and after this i will get a RS125. i am a little nervose about going out on the 'BIG' race track but itll be fun, do you thing i will need a steering damper on the CBR??

[FROSTY]

nope. Look dude ya just wont be going fast enough to need it.

[R6_kid]

after taking my zxr around pukekohe all i can say has pretty much been mentioned. Just remember its important to let your tyres warm up...

Umm also the bike should have a fair bit of lean in it (about 50degrees i think) depending on the tyres its running, so you shouldnt worry too much about leaning right over. Also dont worry too much about hanging off the bike, it is pretty light and doesnt need to be hauled around to much even tho it is fun to do so. Other wise just stay tucked in for the straights and wider corners.

Other than that, when you do decide to brake heavily say for a hairpin or sharp corner remember to sit up again, get your centre of gravity up, as it will help you 'tip' the bike in and will also help with slowing you down. But on the same note, use the engine for braking - on a 250 you arent too likely to lock up the rear wheel. I found i was going thru corners at around 12-14k on the ZXR which means you have really good power thru and then only about 2-2.5k to use before changing.

But other than that spend a lap getting used to the bike, another one or two scouting the track as you get up to a decent pace. Then do as a frosty has said to you.

otherwise have fun... wish i was in your position, even if it is a CBR :niceone:

The cibby doesnt need a steering damper unless your one of these people that run flat tires. With 207s or dragons keep the front 'at least' 34 psi and dont slam the throttle shut. The tire deformation on loading if the tire is too flat is enough to shake the bars quite violently, but if your smooth its fine you'll never encounter that - I found an extra 2psit above the recommended 33 on the front was enough to sort it out.

Ok if ya wanna get serious then start out as ya mean to carry on.
Buy yaself a hardback A4 lined book. Note down the bike/weather tyres and tyre pressures. See ifr you can get someone to get lap times--start and end of day.
I'd wright down how ya feel and what you fel your strenths and weaknesses are.
Its sorta meaningless atm but itll be a good reference point for the future andwill get you in good habits.

[Sketchy_Racer]

hey thanks guys

yea i already got a book that i use for buckets i record temp, presures,etc. some of you may know him but Bayden Sprozen (F3 a couple years back 2nd place national) helps me and gives me a few hints now and then, but cause i race him, and he wants to win, he wont tell me everything, but i am getting alot of good info here. all the info is going in the 'book' for futre refence. :)

[FROSTY]

Now this bit is VERY VERY important --Ir a guy on an old black zimmer frame (SV650) with the number 20 on the front passes you or you catch him
SHOW HIM ALL THE RESPECT THE VERY OLD ARE TO BE SHOWN
heheheheehe--
Note to self -head fuck all possible F3 competition
