Finally a heavy duty kit to replace the Doppler clutch pulley weak stock 6mm shoe posts that bend or break under big power. Soon available at Treats www.treatland.tv
Here’s the final version with water jet cut steel triangle brace (installed on the pulley) + machined steel 8mm posts heat treated + 8mm castle nuts + cotter pins.
The thicker base of each post allows the shoes to fit deeper inside the clutch bell for more grabbing surfaces but with enough clearance so the posts don’t rub against the bell. There’s also a special flat section to hold the post with a wrench when tightening the castle nut.
To upgrade your Doppler clutch pulley remove the stock 6mm pins, drill 5/16 holes, tighten the heavy duty 8mm shoe posts with the castle nuts and cotter pins needed for safety. Install the clutch shoes and the triangle brace plate with the stock Doppler circlips.
Et voila, you’re ready to rip!

Peugeot and Motobecane Doppler clutch pulley available at TREATS www.treatland.tv
So this is it. I’ve made the decision to use a motobecane Av10 moped frame instead of my Hodaka motorcycle top tank frame. It will be lighter and faster.
I’ve got 2 months to cut, grind, weld, order all the missing parts to finish the project and register the bike as a moped by the end of March for the “Super Sunday” big Ruckus ride in Los Angeles.
I’m super excited about that project but no more talk, it’s time to build.
Engine:
Two stroke minarelli horizontal scooter engine 23hp imported from France (Mbk nitro/Yamaha Zuma) with Malossi MHR 77cc h20 kit, Malossi crank 85mm, Stage 6 digital cdi, Dell’orto 28mm carb flat slide, Stage 6 R1400 exhaust, Malossi over range transmission kit, Stage 6 clutch pulley, Stage 6 gears.
50cc single variated moped racing was big in France in the 80′s and 90′s but slowly died early 2000 because of the scooters and 6 speed bikes becoming quickly popular among the new generation more interested in drag racing with 80+cc set-ups.
In 2007 moped racing made a slow come back with old school tuners/racers and few young racers. Since then, the sport has grown every year but still needs new blood to survive.
For the first time this year, companies like Bidalot (pioneer of moped racing and #1 brand for performance parts in the 80′sand 90′s) are stepping in wanting to help the sport grow, by submitting their ideas like introducing an open class up to 80cc the most popular displacement among young racers today (scooters/6 speed in drag racing and speed track racing). The idea is not really welcomed by the hard core an long time 50cc moped racers but could attract new racers to secure the future of the sport. Some argue that Bidalot has always been only about business and fear that they want to jump in just to tap into a new market to sell their modern racing parts, with a risk that they could start controlling the rules like they did back in the days.
The 2012 season is going to be the busiest since 2007 with about 30 bikes in the 50cc open class (no cases and carb size limit, open chassis) in the northern championship with top moped racers traveling for Belgium to challenge the french racers.
The southern championship is packed as well with new crazy bikes this year in each class, 50cc open, 50cc gr1, and the most popular 50cc stock-ish.
Reading all the french blog we can feel that everybody is excited and starting to feel the pressure, working hard to finish their bikes on time for the 1st race starting late march. Some of the teams are even getting a sponsorship this year, that’s a good sign.
Some random pics of current race bikes and new projects under progress, mainly from Northern France. Some of those guys are getting serious for the 2012 season, bringing out the big guns! I’ll try to plan another trip this year and go to one of their races, last year I went to one of the Southern France championship event, gained tons of experience and brought some cool moped parts.
This is a Peugeot bottom end engine I properly reassembled today and ready to ship back to Canada for a top tank moped project.
Some people still ask me if we build moped engines for others, I hope this post answers the question.
I’m specialized in Peugeot and Motobecane variated engines my first choice of mopeds but can also work on Puch and Tomos engines stock or kitted.
Just email us at tomahawkmopeds@ymail.com for quotes since every engine project is different and send us your parts or ask us some advice on what parts to buy.
And YES…. we can build your custom moped too!
Keep in mind that a vintage custom moped built from scratch with brand new parts is not cheap and to build it right with quality like all the Tomahawk bikes it takes an average of 50+ hrs of labor, that’s if there’s no special custom frame modifications request.
For example:
Just a vintage moped frame can cost up to $200, good mag wheels $200, Ebr fork $200, disc break assembly $200, standard rear shocks $60, handle bars – controls – head light – cables – pedals – chains, seat, etc… another $200.
So a $1000 just for the rolling chassis + paint job.
Plus close to $1000 in parts for a fast brand new race engine built from scratch. A brand new stock engine is a little cheaper but still around $600 in parts.
Here’s my personal experience:
The fun thing about mopeds is that it’s supposed to be cheap and do it yourself. Fast vintage custom mopeds are a whole different world. People buy a cheap vintage moped and try to learn to fix it themselves. It’s fine as long as they keep the engine stock but once they decide the bump the power with performance parts, it’s just the beginning of a long, painful and expensive road.
Over and over I see people wanting to build their own kitted engine to learn and save money. But most of the time they end up spending more in the long run after seizing multiple kits or breaking their engine parts. After few months of frustration, they finally bring the bike to an expert which they should have hired in the first place to really save money. It takes even more labor for a mechanic to repair a damaged engine than building one with new parts.
In conclusion, their is no cheap vintage custom moped and fast. The only cheap moped is a stock vintage one which you got a good deal for and that only needs little maintenance once in a while. Or, a brand new Tomos stock-ish engine reliable with a pipe and up jet for daily commuting at 45 mph max, and maybe little extra money spent on chassis parts to make it look less boring and more custom.
That’s just my opinion but I hope that it helps those who are new to the moped world or want to build a custom bike.
Among many brands, a Bidalot 50cc and 70cc kits for 6 speed minarelli AM6 engines.
Plus, French-German company Maxiscoot/MXS racing latest prototype with their new 90cc kit (2 years development) available on the market by 2012 for minarelli horizontal scooter engines and 6 speed engines like minarelli AM6, Derbi euro 2 and Derbi euro 3.
Can you imagine that sweet 6 speed 2T euro technology available and easily adaptable for our french variated mopeds? Hmmm… let me see if I can work on that this year.
Look inside Maxiscoot/MXS custom shop, working on their 1st air cooled 70cc kit 18.5 hp one of the most powerful for vertical minarelli Zuma 50cc scooter engine.
CNC machined aluminum clip-ons made in USA for 28mm EBR hydraulic forks and most stock moped forks.
Fix 8 degrees race angle.
Standard size 7/8 aluminum tubes 12 inches long. They can be easily cut or replaced by any chrome or black steel tubes from cut off moped handle bars.
Perfect for your street custom project or race moped.

This is what I made with a friend and my son of a 2005 Ramzey Comfort (which is a Turkish Peugeot 103 clone with kick start as you might know).
We’ve built the moped for my girlfriends son’s birthday next week. Today was the first time on the streets of Amsterdam and it attracted a lot of attention from passers by.
We bought the original bike for €50 and managed to keep the total cost at about €250, by using a lot of second hand stuff from adds on the internet.
We visited the tomahawk website often after my son discovered it last year when he got an old Peugeot 103 for his eleventh birthday from my father as a learning project.
Through this email I’d like to thank you for the inspiration.
Keep up the good work!
The 1st batch is here! The clip-ons will be FOR SALE very soon here on the Tomahawk blog and at Treats www.treatland.tv
Working late nights getting the clip-ons ready, compressed air cleaning, thread and quality control, aluminum 7/8 tube cutting, Allen screw assembly.
Perfect racing position with a fix 8 degrees angle just like on my Peugeot 50cc race moped.
- BONUS PICS:
Sneak peek at the “Transformer moby” project by Overkill (chassis) and Tomahawk (race engine).
Engine set-up:
Stock av10 cases ported, Doppler kit 50cc air ported, Malossi crank, Doppler stock reeds, Dell’orto 19 carb, Doppler pipe, Mvt cdi, Bidalot Junior variator, Doppler clutch pulley, stock engine spring, launch lever. Probably an h20 50cc set-up in the future.
Check out the size of that fat rear tire (3 inch tubeless) with the wide stock mbk av10 magnum square swing arm! I can’t wait to see the future gas tank side covers with aluminum CNC machined motobecane raised 3D logo.
Engine cases disassembly:
Case matching + billet LED tail lights:
Cylinder porting:
Setting the transfers and exhaust port duration at Gr1 moped racing specs + Bidalot variator.
VIDEO:
The engine is built so tight with precision.
All surfaces were carefully checked. The crank perfectly centered. The cases are assembled with special crank seals not available at any moped part store, new grade 8 7mm bolts + stainless steel spacers. The head is mounted with malossi long nuts M7 and stainless steel thick spacers + O ring and professional super resistant sealant. The squish is safely set for 91 octane fuel. Blue Loctice applied where needed.
Next is the ignition with timing set for high rpms + aluminum welding inside the intake manifold to match the stock reed block for a perfect gas flow.
Even though the cylinder is not lubricated yet on that video, the compression is already very strong! Just what we need for crazy 50cc power.
PS:
I’m getting ready to build my cafe scoot /drag ped project powered by a minarelli 77cc 23hp dual variated scooter engine. I’m still undecided and looking for advice. Please check out my last post on mopedarmy to help me take a decision, thanks.
