troy lee pred question
The two trannsmissions for the pred from '05 - '06 were the close ratio, (TLE & '06LE) and the wide Ratio, (STD and '05LE)
The close ratio has 1st - 4th being VERY close and the fourth only winds up being a touch higher than the third in the wide. Then fifth on both trannies is the same ( i can post more information in a little bit, it's not available on this computer, but i've done LOTS of calculations to help you see the differences)
Essentially, just from riding them, i can tell you the big difference is that the close box is much quicker through tight courses and through woods, but if you have a very wide open race track (like flat track racing or running through feilds) where the Wide gearbox can stay in fourth for a lot of the time, you will absolutely WALK a close box, because the gap from 4th - 5th is too big on the close box. If you can't take advantage of this for extended periods of time, however, wide open field - type running is about equal. I'll post ratios, and max speeds in each gear for each box for each in around a half hour (if i can find them) or an hour if i have to re-do it.

Calculated Max speeds in Gears:

4-------------------------------------58.4---------------------51.3---------------------56.3-------------------61.4
5-------------------------------------69.0---------------------69.0---------------------75.0-------------------75.0
NOTES:
1) The KTM's speeds were omitted b/c i don't want to start bash sessions if i don't actually have data on the machine, however if anyone would like to know i calculate its top speed to be a tiny touch higher the Pred, but there are a few problems with the calculation that i think make it not valid for the 525, namely i don't know how far it will wind out in 5th. The top speed of the pred is not necessarily limitted by the rev limiter as it will not really rev all the way out, (in my 200lb exerience on flat pavement, it won't quite hit the rev limitter) This also kinda hurts the outlaw 500's top speed calculation, but it's close and percentage wise, the gear split is accurate.
2) I assumed as a basis for calculation: the Predator's top speed was 75mph and this occured at 9100RPM (which is the rev limit.) i realize this is not PRECISELY true, but it's the closest i can come up with, because variences in this assumption are far too many to account for and people would be pissed at me for being so absolutely sure, what the pred's top speed is when they're sure their cousins goes a hundred according to grandpa's old ford's speedometer.
3) The Outlaw's top speed is actually a tiny bit over 70 in my experience, so obviously using the pred's top speed for calculation of the outlaws has some minor flaws, (coverred in the last 2 notes). However the purpose of these calculations was to show gear split, not really top speed.
Interpretation:
As you can see, the gap between 1-2-3-4 on the close box Pred is MUCH closer! it's very tight, and very quick through those gears. You can also see that gear 4 on the wide splits gears 4-5 on the close, which is why it is the one gear which (if you can keep it there for long enough) will allow the wide to walk away from the close (both in theory and in practice, we've performed lots of experiments, conditions have to be right, but the difference is profound in wide open, flat field racing). hope all this information helps [img]i/expressions/face-icon-small-happy.gif[/img]
Another intersting fact:
As you can see from the data above, the '07 Outlaw' transmission seems to resemble more the wide ratio tranny than a close ratio one with a lower fifth. I think the '07 Tranny would be much nicer for wide-open areas, for the reasons stated above, but the '06 might get it in tight woods. just an interesting difference, probably not profound, but were it me, i'd prefer the '07's box. Anyway, good luck w/ those numbers, post here with disputes as i'm sure there will be some...
P.S. Isn't it nice to have engineers in the forums? [img]i/expressions/face-icon-small-wink.gif[/img]
