mopeds


polini cup round one

I’m home, tired and don’t want to study, so lets talk mopeds some more!

Me and some superteens went out to atwater for some good old fashioned fun, because what could be better than mopeds, racing, hanging out, and super target, all 2 hours away from anywhere you’d actually go if you were a sane being. Of course we got there late, and of course the mopeds were on the track at that percise moment, so I missed practice. I wrongfully assumed it was like last year with 4 practices, but nope, this year it was 3, so I was down to 2. I was a little skeptical of the magnum (derbi?) just because I knew I’d be abusing the za, so I “tuned” it up (set the timing and “jetted” it, meaning it was good to go!), then got out there. The n8p was pretty dismal with my gearing choice (18×36) in that it would downshift on the hairpin and maybe the big wrap-a-round left, but otherwise I’d be in 2nd with no power through the turns. Not good, but once it hit on the straight, it went pretty fast, seat of the pants maybe 60, but probably more like 55 or less cause I couldn’t top it.


Rafter was really cool and let me throw a spare destroyer on there for the next one, and boy, what a pipe! I’d always kind of just dismissed destroyer power as a fad (really I’m just too cheap to lay down the scrilla), but it holds its own. Similar in its hit to the circuit, but later, and if you tempt the za long enough, it’ll pull through the band and shift right back into it. Fun stuff!

As many are likely aware, there were some rad builds this winter (or last couple weeks), and all were quite impressive. Jimmy and Tony worked together to build a pair of identical awesome flat-reeders. Each is stroked out, ported all nutty like, tuned pretty well, lightened here, strengthened there, and a custom pipe finishes it all off. This things are next level, and both definately have the potential to deliver some quick laps.


Tommy built a vogue, but got the massive mikitech cases and clutch pulley, is running the derbi metra, a 28mm flatslide among other insanity. Its fast, and when its fully tuned and ready, it will be head to head, power wise, the full length of the track.

Dean built the VX4, the most unique moped ever. It has a pinto frame, hobbit cases, derbi cylinder, moby crank, moby er3, derbi rear pulley, hobbit front variator and clutch, hobbit rear pulley and wheel, HPI, hydro ebrs, custom subframe, in-frame gas tank, and probably many other things I forgot. Regardless, its got the potential to eat every moped. The 2 pulley sets variate sequentially, the rear after the front, so tuning is a bit tricky. Unfortunately the bike sustained some damage in the 2nd practice, so he was out for sunday.


With so many (should have been more) amazing bikes, the racing was amazing to watch. Jimmy and Tommy are so competitive, and both go all out. The derbi’s would take the straights but tommy would always be there in the turns and made passes then was passed and so on, and some how Pete got up front on Tony’s monster. Rufus was out there on his bravo as well, not quite as fast, but he gets quicker every lap, so he’ll be exciting to watch.


This beast was 62ccs, something like 6 or 8 hp. Nuts!

I managed to win the e50 polini class as I violated every rule in the book. CDI, disk brakes, 24mm carb, za50, all prohibited, all present. I managed to score a sweet 2 foot trophy and some points. Kick ass! Best of all the bike survived. My fastest lap was 47.something, not terrible for the bike (last year I think I got down to 43 on tom’s derbi, this time the fastest in open was around a 42, and last year the fastest fast was about a 40 by jeff) And for those wanting to race, top tanks are worth their weight in gold. So nice to have something to hang onto. For Gabe, I forgot to check my main in the flatslide, but its either a 165, 180 or 205. Sorry buddy!

So I’m pretty excited for later races, and I really hope more people head out. I’ll be honest, its pretty lame no one showed up. Obviously we all have things going on and whatnot, but come on. We have restrictive rules created for a race with 2 people showing up to ride? That’s exactly the point I guess. Even if you aren’t building something crazy to battle the fast dudes, get out there. Track time is a lot of fun. I’m bummed I have to miss the next one, but I am more excited for June.

coolest moped ever?

so my buddy matt (who rode my dying derbi at the 1st polini cup) has just about finished his amazing new derbi/garelli sslx combo. The bike is amazing, with a flat reed motor, 70cc metrakit, lomat 4 petal, 24 mikuni and a big zen pipe. He’s got nice EBRs and its fitted with derbi spokes. Regardless of all that maybe cool stuff, its an awesomely fabricated and proportioned bike. Its super low and very solid. The front mount is all fabbed up and nicely welded by one of our race car building friends. I dunno, I guess you’ll just have to see it at the polini cup to appreciate it. He says he’s got an amazing seat coming for it, but I dunno, I feel like that will make or break the bike. Heres a photo in its mock-up state, I’ll give more when his seat arrives.
