Chennai xBhp Track Day - 22 Feb '09 - The Discussion and Pics thread

@ killer, I never felt that C8 was a tricky corner. But after the incident, I am feeling so....How do you approach this corner? you brake or downshift ?

[wonderboy_tm]

Yes i think it will help but more than that you have to get over the fear of what happened and regain confidence in yourself.

when are you coming down next time???
i want to follow your tail around the track. Initially slowly and faster after a while.

Its tricky because it gives the appearance theres more room on the exit and you dont realize until too late. It also has a slight negative camber on the exit.

You're coming off a long straight in a high gear to a very tight right hander so you brake and then you downshift. On a fast lap i trail the brake till the apex but then thats not something you should be doing right now, so dont worry about it.

I'll be down soon for practice and you're welcome to tail me, the only problem is i'll be on a R6 and the lines are slightly different, i'm not riding the small bikes anymore. We can definetely do a couple of slow laps together nevertheless

I would be privileged....

At c8, even i had a tricky moment... thankfully i was on an r15.... i was able to brake mid corner..... would it be appropriate to enter the corner in 4th or 3rd......

and on the R15.... the chicane before the bridge..... which gear are you supposed to take it in.... i guess there is a lot of shifting required on an R15 when compared to the RTR ???
I am DEAD slow at that chicane.....

[narenr_nair]

This thread is fantastic and those pics give us less privileged people a much better idea of what we are missing...

For reference sake, heres something i had put together for someone who wanted to know the gears and speeds on a fast lap at chennai aboard the R15. Use it as a guide to help you know where you're moving in the right direction and where you need work.



Below is the correct gear pattern used by myself and other experts, also the speeds that I touch at respective points on a 2min 15sec lap aboard a stock R15. All of this based on the track diagram above:

C1 – 6TH gear under the MRF arch, around 127kph before tipping it in under the arch and full throttle all the way through

C2 – 4th gear, around 92kph at the exit of the turn

C3 – 4th gear, around 88kph at the exit of the turn

C4 – 4th gear from 6th

C5 - 4th gear, exit speed around 97kph

C6 – 5th gear

C7 – 5th gear, exit speed around 111kph and 126kph at end of the straight before braking

C8 – 4th gear from 6th

C9 – 4th gear, around 109kph at the exit and shift to 5th shortly after exit

C10 – 4th gear

C11 – 4th gear, around 89kph at the exit (half way up the bridge), shift to 5th just after top of the bridge

C12 – 4th gear or sometimes 5th depending on how fast I want to enter the turn, exit speed around 107kph. (If taken in 4th I shift to 5th while exiting the turn)

and that’s a FAST lap around the Chennai circuit aboard the R15

Im not going anywhere near the circuit without tailing you atleast for a couple of laps Killer.
The next track day that us Bangy guys plan, you just have to accompany us please. Im sure there'll be no wipeouts then

[M@n()J]

Thanks for this new thread....

@Kushanth:It was on me the blue 220 whom you mentioned in the other thread...

Damages to my 220 after the crash - RHS Fairing bent inwards, crash guard bent, RHS clip on handle bent, deep scratches on the silencer. Should get my bike back to shape now.

[wonderboy_tm]

6TH gear under the MRF arch, around 127kph

i'm not riding the small bikes anymore.

what wrong has the small bikes done to you that you have decided not to touch them anymore

Will try my best to be there next time. Its encouraging after so long that people are finally getting on the trackday trip and better / safer riding.

honestly.... i never used the 6th gear at any place.....
i was a gear lower at C3, C4, C6 & C7 (now i know why the bike hits the limiter there), C8, C12....

yeah
almost everywhere......

Nothing wrong, i've learnt a lot from the small bikes. Its just time to move on now and theres lots of work to do on the big bikes, they need a different riding style /technique that i am working on now. Riding the small bikes now will only interfere with my progress, hence the decision. I'm not quitting riding small bikes on track, will definitely so do for entertainment but not right now in the run up to the race season.

Dont use the gears i've mentioned just because i said so, you need to work up to carrying enough speed to require using those gears. Till then just use what i posted as a reference to tell you 'where you are in the ball park' and 'where you are loosing / not carrying enough speed'.
