DRR transmission

[riding4fun]

I keep reading that the DRR and others including the Apex have the same transmission. If that is true why don't I hear of more transmissions breaking, gears etc...

What is available to strengthen the transmission?

This is my education for the day.

Thanks

Nevermind I found the info I was looking 4

DRR is working on somethings that have not been listed in the link you posted.


After they are tested I will post results

We carry a kit with every thing need to stop breakage. Comes with Press in bushing, case saver and sprocket. Cant count how many we have repaired with super results.

You can use an INA NK25-20 needle bearing to replace stock along with a tranny saver. This will eliminate the friction of a bushing but still not bullet proof nothing is. whatever you use change gears every 4 motos thats what I am going to do. 2 of us broke gears running 1-2 last weekend using both combinations of needle bearings and bushings.

YUP, had the best run ever going too!!!

We installed ecmini s bushing and have had no problems. One bike we run against just broke a second set two weeks ago running the new bearing. We have over ten motos, practice time and dune trips on this bike since we installed the bushing with no issues. Maybe Shayden doesnt push as hard but with his record I would have to wonder. Now watch I probably jinxed him. Go with the bushing mod.

We have ran into the same thing and have that needle bearing as well.
We have everything fresh and new and was very close to losing another tranny this past race that only had two races on it. (done a tear down and found this out a couple days ago)

Also,the shaft and the bearing pushes into the tranny cover bending the washer on the inside.
Has anyone ever come up with a solution to this problem?

Glad to hear you all are doing well.

We just broke our first set of gears in the drr after 5 months while practicing MX. We usually race Harescrambles. We will be testing the new forged gears. They will be in today. I will give you a full report.
I know it has been said over and over again, but if the kids would stay off the gas while in the air, they would never break.

There is alot of truth to that, but thats not sole cause for it to go.
Ive seen them go regardless .
All the mods to the tranny help, but even with all the mods to the tranny,nothing seems to fully remedy the problem either for some .
