Bike is a 04 cr125 mod bike will get the 05 engine. Another 04 I would have a spare engine also. I have a lot of parts for a 04 pistons, clutches, gaskets, cables,etc when pistons r used up use oem pistons there cheaper. I could match everything chassis wise except the rg3 triple clamp. Just ride the mod bike a little bit during the week. Practice 04 would get porting to run 50/50 or less 110 leaded I can get it at the pump. Basically ride the practice bike a lot and save the race bike for the weekend. Suspension rebuilds is just 1 of many reasons .
But honestly I can't see any cons either, are there any?
. Basic stuff has to match. It would b great to go play ride also and hit trail loops.

We use a larger bike for practice days, so when race day comes the smaller displacement bike feels like a mini bike and you can ride it WFO to its full potential.
We use 450 and 250 though, so it may be different with two strokes..
Con: all the women throwing themselves at you gets tiresome
I mean as long as the bars / pegs / controls feel familiar and the mechanical setup is close so it's not a total culture shock, is it not more about the time on a bike than time on a total clone?
Brent's point sounds a good and pretty commonly done too, CR250 that feels familiar could be beneficial and cool to have both as well, in case you go somewhere mega deep or want to race a different class. Like 250 guys riding four fattys through the week.
I tried it different the next year. I bought a bike, set it up, stocked up on spares (which I already had thanks to Yamaha leaving my beloved YZ250 alone), and just repaired everything the second it came up. There was some rush jobs due to one off accidents. And I had to do my own suspension rebuilds to avoid lead times. But I kept that bike for half a year and did it again for the second half. Swapped all the bolt on stuff, put the stock suspension from the new one on the old one to sell. I came out way better dollars and cents-wise and it was way less stressful than having two broken bikes constantly.
My two bikes are 2016 KTM 125s. One has a full mod motor from PC that is an absolute rocket for a 125, and the other one is pretty much bone stock other than similar suspension work as the mod bike. It was really nice to have the stock 125 for a practice bike because the intervals were way more spread out for actual engine work, I could rob parts off one another for a day if I needed to, and worse comes to worse I could save one of my friends days if his bike Peter’d out on him.
It was really nice to keep the hours off the mod bike. Nowadays I don’t race very seriously so I’m rebuilding the old practice bike into a 150sx woods/GNCC type of bike and will keep the mod bike strictly for winning practices at the local tracks.
I know the Hondas are dear to your heart Profeshenal, some of me agrees with the above posters saying to get a modern bike but I miss my 2006 CR125 everyday, outhandles my KTM or any YZ I ever rode. Slow as a dog though.
Keep on Truckin.
Sell me the low hour 04😊
. Then hv a spare 04 engine. 05 engine is quite a bit lighter also.
Pit Row
Available.
This I got my cylinder back in aug or sept then I was gone. Last yr I had a metal bur in the hole for the pv shaft. Long story but the 2 screw drivers to keep the pv half’s off the bridge. Bent it with a time crack. I drove it to millennium after a few days I called. They need to order the piston. I was told there would b a quick turnaround for a local. I also mentioned I want to hit a couple big races b4 winter. Close to s month b4 I got it back, 23 riding was ovr. This yr a disaster for work, money, injuries. Wanted to get the cylinder on the practice bike hit a track with sat practice then race sun. Weather here was freezing , rain , busy with injuries, etc. I finally got the bike together sat . Trouble with the rear tire 3 hrs, tube blew when I was letting 55+ psi out. Steel a tube from a oem 04 it leaked air off fast. I had to pump the tire up after a warm up then rip. C12 is 15 months old bought in bulk it was in a vp can tho. Turned gas on 3 quick kicks and it fired up. Off idle snap is great and the bark sounds tough. Mid to soft tire hooked up great in the grass. Quick stab of the clutch and 19 lbs of instant quick hit then a fat torque pull that keeps pulling , still pulls on the ovr rev. Best to stab clutch 1/2 a sec later up shift as fast as you can . Quick and strong & very exciting to ride. The clutch all oem only 4 rides started fading in Honda like. Bottom end & frame is practice bike, linkage swing arm mod bike. Mod bike cases r split that’s why I did this. I had to see how the DBP ran . I think the fuel is stale . Fmf fatty with a shorty , rad valve , iKat . I see a good jump off the gate next yr. Quick with zero wait to build power 19+ ft lbs Rt now. Perfect LL engine

Your loyalty to Honda is baffling…they left you out in the cold with no 2t production…buy some Gas Gas 125/150”s…..and enjoy life…. I see many ex Honda loyalists riding gasgas…. Something about the color red that makes them feel better…
It has nothing to do with loyalty. It’s about comfort the bike fits me like a glove. Handling is better than any bike ever made. I hv the quickness & power advantage from the hit to 12k. This engine spec was hole shotting wmx pro races against 250f,s. And won the women’s LL title, Last cr125 to win a major title. You hv any idea how much Fun it’s gonna be , ripping hole shots on a gate of 28 125,s. From the hit just above the low end it’s hyper quick with quick torque and pulls hard to the ovr rev, short shift or rev it out. In other words easy to ride if your quick . 2nd or 3rd you fight to keep the front wheel down. Hv to update the clutch with the Super hyper pull best way to explain it.
Carb has a different taper bore too, forgot that. I hv to figure out why the rear brake hardly works, it has 5 hrs on it.
When I get the mod cases on it , it’s will b more rippy.

Oh man don’t open the polished cases can of worms.
There is nothing in the world better than a well-built 125 that does exactly what you want. It's surprising how fast you can go on one.
Profeshenal, where do you keep your bike? On the truck? In storage? By your pictures, it looks like you're doing a complete teardown at a truck stop somewhere.
I did the opposite.
I raced both 125 and Open and during the week rode only the heavy open bike and when race day came the 125 felt like a toy with no HP.
Storage unit it’s near the bay so it’s windy and cold a lot. I called the iL. Labor dept to see what’s going on with my unpaid wages. That would b a nice AX racing budget . Holeshot money would b nice to add to the 14th place 50 bucks. A 125 mod to run on c12 is a blast. Just north of rd America Waldo, Wi. C12 in bulk is 7.00-7.50 a gallon. The office is a house close to the st in a tiny town . Older gals a couple big dogs. Pay for your fuel then they meet ya out back in the warehouse. They hv hundreds of barrels of VP. Cool as hell

I Love those 93,s actually 92to 97. I rode a pc 97 it would surprise you on how strong they pull. The 04 Way stronger, quicker & pulls longer. Feels like a quick 150but revs like a 125. Real quick and torquey. Millennium matched cylinder to a Wossenger piston. Tight tolerances I didn’t think it would go together. Fmf pipe hits hard the 03 kx hgs Budd pipe has less of a hit but pulls into 14 k land.
