I also did a 94 Pro circuit KX125 to the same level of detail that i raced once last year, and i'm about to start on my next one that will be the same as this too
I think the modern A kit on that light weight and powerful motor (gonna go ported race fuel only 144CC Mid-up power band) could really be a hot setup!
185? 188? pounds with close to 40HP? Can it be done?? 20 years old and kicking ass against these UNBEATABLE UNPRECEDENTED 4 strokes? lol Anyways awesome build and I may have some ???'s for you as I go along with mine. haha
Cheers!
Overall very nice build.
The Shop
By the way, i'm actually building another 92 Peak CR125 at the minute. I won't be doing another build thread as it's going to be basically the same spec/quality as this one, but it'll be one i can race next year in the UK Super Evo Championship and Farleigh VMXdN. Based on that i'll be running a few non PC correct items to improve performance like this nearly new 91 Mugen Kit i've just got my hands on, but i'll try and keep it as accurate as possible.
This bike won't be ridden. I cant bring myself to take it out the workshop, too many new, rare parts that would be a shame to ruin.
Hence the reason i'm building a 2nd 92 peak bike to race. Itll be built the same but with the odd part swapped for performance purposes like Works connection clutch perch setup, mugen kit etc, and more original restored parts as opposed to NOS parts like the tank and airbox etc.
With Round 1 of the UK Evo MX Championships fast approaching, ive had to crack on lately and get things moving
Anyway, tank and airbox refurbed by Holab Concepts (highly recommend!)
Pit Row
- Vapour blasted and powdercoating done by MHF Restorations (always an incredible job as usual!)
- All new OEM Honda bearings/seals/gaskets
- Vertex 22190B Race piston modified to match Mugen pistons
- Modified Governor to retard powervalve opening
- 98/99 Powervalves
- Keihin PJ 38mm carb with new Choke, Slide, and all jets
- New modified Vforce3
- New clutch kit with Billet Wiseco basket
- Full Titanium bolt set
- Custom billet Pro Circuit Igniton cover
- New OEM Rad hoses and clips
- Endless OEM internals
Hopefully have finished bike photos tomorrow, and i'll make sure to get up a video of it running too.
The pipe is a new pc of which I am sure isn't correct to the actual race bikes. After a little tuning on the dyno I think it ended up around 34.5 ish hp off the top of my head. His 2003 all stock motor with some reeds, pipe and silencer (pc pipe and silencer was light years stronger than both sst and fatty on this bike for whatever reason) makes more hp but less area ubder the curve than the peak bike. The peak bike was similar to a new stock yz125 with some advantages in a few areas making it a very usable power, in a racer x article mitch said their hondas were 35 ish hp and the switch to kawi was a hurt to them..so all in all the owner was very pleased after reading that article. Of course before the dyno time he was certain it would be 40
he has a couple mugens of various years and some incredible elsinores and early 80s model bikes
Your build is beautiful
