Nice video’s boys couple questions What is the real advantage of the frame and do we all use 5 tyre leavers to take it off instead of just 2?

5 work the same as 2 Corey its just easier when you have them with you. The frame only helps hold the wheel, helps you back and makes breaking the bead easier.

Why toque multiplication was even mentioned is beyond me. We are supposed to be giving advice to a average Joe (no offense Boonster) dirt bike rider. Like a lot of other threads someone has asked what is a relatively simple question and has been provided with wild answers.

Torque multiplication matters on a BMX because the 45Kg boy riding it puts out about 0.2 horespower and needs every single mechanical advantage he can muster. This can be considered an ‘extreme’ end of the scale where a small mechanical advantage can make a noticeable difference. At the other end, drag cars, high powered engine etc. it is also noticeable as the they measure performance down to 1000th’s of a second.

Let’s be honest, torque multiplication makes f’ all difference on dirt bike when changing from a 13,14 or 15 tooth front sprocket.

If you are going to worry about that there are heaps on other things like, fairing drag coefficients, tyre pressure, bike weight, rider weight and heaps of other factors that can be looked at and have a more noticeable effect on performance.

Remember we are giving advice to dirt bike riders, not moto GP riders.

:laugh: Thats true Moto that said for all my years around bikes and races and lucky enough to be around some major race teams I have never seen them talk about final drive ratios as you put up, although I am sure they all know how to work it out and it works.

Its been a great thread and I think on small capacity bikes it all matters, bring on the learning I say

Yeah he won the 2006 A4DE Crash and I only saw him at the riders briefing :laugh: He smashed the field including all our local fast boys, our GNCC boys and Shane Watts on a new 250 four stroke Kato

Fast

Boony will a 15 fit on the front of a DR? The reason I ask is because as you know a front wears faster then a rear, normally two fronts to a rear (three or more with quailty rear sprockets)

Hey Menace & Co remember at the riders briefing they talked about people riding the tracks as they tried to arrow them on the saturday and having near misses? what schmucks :laugh:

T/B is indeed correct about torque values on front sprocket size.

We did the same with the kids on BMX bikes, long crankarms as practical for little legs, and as small a front sprocket and compensate with the rear to retain the optimal gearing… a very switched on bloke showed me this years ago.

But as also stated small front sprockets wear chains faster.

Exactly Bruce, thats a great example

One other important thing no two bikes are the same or ridden the same. Even same models, riding styles one has a pipe or jetting kit or both, one guy revs a bike more or rides a gear higher.

Chops Banana was such a pig of a bike until we geared it up (smaller rear) The DR engine is a torquey engine and has a stronger mid range then top end thus the gearing change opened the broad power in the middle of the rev range up. It still climbed everything and was better it the tight going of the pine forests in Orange, 2nd gear instead of 2nd, 3rd, 2nd, 3rd easier to ride. I was lucky to do 1000 odd kays on it

Good luck Boony working it out and learning for yourself is most of the fun IMO

Good on you Drew, congratulations on winning the tyre etc. There is more to you down the bank, I have a contact with a picture that he has promised me so wait for that. Glad to meet you mate, now organise your ticket for the lunch.

Hey Jak thanks for the idiot call I was clutch starting my bike and it fired, if I was roosting you it would have been more then that ask Choppa :laugh: And Chopps front tyre roosts good

And what superman jumps :huh:

Nice videos as well mate the sound is great compared to mine, it gets so much wind noise

Good job Boony will do mate

we should do a seperate one for the Ks travelled by car on the same weekend, just to see how far we travel to enjoy our hobbie.

Just a thought

Boony

Boony thats a great idea mate as well, be very interesting If we PM them to you can you add them up and work them out and STM with the others?

I am going to put the dates of July 3/4 as the definates for this. That means that you have to log your k’s over the two days and if you don’t have a speedo then either ride with someone that does or give your best guess. It is 16900k’s from Wauchope to London so if 75 Old Bulls all pitched in 225k’s over the weekend we would get there.

I will post a few reminders as we get closer to the date and you can PM me the number you do. Remember you can also guess how many K’s you think OBT can cover in two days and the nearest guess will win a prize.

Thats awesome Scott, great job mate I cant wait to see how far we go

G’day TB I heard on the weekend that Dave Philips at Blue Mountains Yamaha in Katoomba has a new black Tenere that he’s lookin to get rid off a bit cheaper than usual. Don’t know the bloke that well but have been on few rides with him and some Bathurst boys a few years. I thought I’d let ya know mate…might be worth giving him a call.

Cheers for that Dusty, will look into mate tar
