Well after sitting in hospital with a sick kid a few weeks ago and going through every build in this forum due to boredom I got the bug to do a build myself.
Then I thought why stop there? Between work, raising two young kids and health problems I’ve let myself go and have gotten pretty fat, unfit and been feeling down about my appearance. So why not build myself as well?
Then I thought about it some more, if I’m going to go through all this effort I should set myself a goal. The mx nationals here in Australia have a 125cc senior class that contests select rounds. I was an A grade junior and it was always a dream to have a crack at national level racing, but life, injuries and priorities got in the way. So fuck it, you only live once. If I can qualify and maintain a decent pace the whole race I’ll be absolutely stoked!
Less about me and more on the bike, I picked up an 02 rm for a decent price and good condition for its age. The bike itself is very rideable at the minute so I’ll do a few good rides and order parts before I fully tear it apart and get properly stuck into it.
I’ve got a few questions hopefully you legends can help out with.
1. Can you put the 05+ barrel and power valve on the 02 motor?
2. Will the kyb sss forks out of a yz 125 slide fit the rm clamps?
3. What is the best exhaust system and carb set up?
4. Can you powdercoat or cerokote a clear coat over raw frame?
5. Could anyone recommend workouts and a decent diet that would help for mx?
Thanks for taking the time to read and I hope to get some great advice from you legends!

I am in the same place, rebuilt a 89 125 honda just to get out and ride again.
Good luck with the build, homie! You picked up a solid bike, GO FORTH!

The young Tacker is healthy and back to being crazy, which means I can waste money in dirt bikes!
Did you do a build thread for the Cr?

I’ve been looking into it and it’s going to be a lot of work, the forks on the bike are 46mm and the sss are 48mm, I’ve got the gear at work to machine the the clamps but I’m not sure how much it would weaken them...... think You’re right about waiting to get healthy. No use setting a bike up to lose weight and have to do it again.
Those are some great pointers, I’ll definitely take it all on board. Would you be able to recommend a mx orientated workout routine on YouTube to save sifting through all the crap on there? Thanks a lot mate you’ve been really helpful.
If you went with it my tip would be do each week twice, back to back. This way you can master the movements and it spreads out your investment from a 3 month to a 6 month program. Then when you’re done, do it again, with more weight or whatever. I think a lot of people get wrapped around the axle with fitness and feel like they need to lift heavy or do what they see these instagram fitness people do. Start simple and work your way into a nice routine and don’t burn yourself out. Good luck.
The mt bike has taught me better line choices,body position and reaction to moving obstacles and works the same muscles as riding. I workout a lot and have to work out daily for work and no matter what I do in the gym, there are lots of muscles you only work on the dirt bike and mt bike.
You can absolutely clear coat over a raw metal frame, I personally think it looks really good..especially if you torch the welds before clear coating.
RMZ forks will work, however you’ll need the RMZ front wheel and spacers and you’ll also need to bore out your triples as the forks are a larger diameter.
I know some RMZ triple clamps will swap straight onto the RM’s so that will be an option if you don’t want to bore yours out. ( Pro Circuit and a few other aftermarket RMZ clamps will fit )
Most RMZ shocks are a direct bolt on fit for the RM’s so I’m sure that’ll fit fine.
RMZ front brake system is also a direct bolt on fit and is a nice upgrade from the older RM brakes.
As for a workout, I have been doing p90x and really enjoy it and am seeing results. I'm now able to run full race length at my local races at full race pace and not be completely puffed out.
Dirt rider did a two stroke pipe shootout in 03, I don't know how the 02 motor compares but it might give you an idea how the pipe works. If it were me I wouldn't worry about changing what you have

Pit Row
It's as relaxed or as serious as you make it. I went there knowing I'd get my ass kicked and just to have fun. The Saturday was probably the best, we rocked up just after all the semi's had set up and it was cool to see the in's and out's of the pro paddock. During track walk we were walking around with all the factory riders and riders briefing was the same.
Sunday was a more serious vibe and there is some fast guys that race it. It's been a long time since I've raced at a bigger event but racing the nationals was cool.
RMZ rear shock won't work. Not without modification. The 02 has a completely different linkage, The 04+ RM is the same as the RMZ's. You might be able to use the clevis off the 02 RM shock on the RMZ shock to make it fit. I had a look at that, and I reckon It'd do the trick.
I'd say the RMZ forks will fit the bottom clamp, but might not fit the top. Good chance you can use the top clamp off the RMZ, I did on my 06 model.
The radiators stick out further on the 02. You can grind the radiator mounts on the frame to make it the same as an 06.
Unfortunately, not many 06 or RMZ parts will fit the 02 model without modification. The 02 and 04+ frames are completely different.
