hobbits are arguably the best mopeds ever made. Once you get the hang of the "difficult" to access carb you'll really love them. They have a carb like you've never seen before. It has no slide, instead a butterfly door that opens and closes. some people whine about how hard they are to work on.. here are some pros and cons.
They are dual variated (meaning a static engine placement, no pivot like the french)
Have cast iron cylinders
Case induction with huge reeds
incredible electronics, points that never die and rarely need re-timing, great lighting.
Stock 12mm carb and reeds are good for 55mph+ and once you get them right, they are rock solid.
proprietary controls (not magura, domino, etc.. however, use super generic cable ends on the levers if you use a knarp on the wheel side.)
hard to access carb which is very intimidating to novices. Its made by Keihin, a massive O.E. manufacturer.
brakes are generally a laugh
cranks are pretty brittle once you reach like level 7...
Bas gas mileage...
From 1978-1979 they were called the Hobbit. they came in RED (PA50-1) and YELLOW (PA50-II). the red ones are slow, the yellow ones are fast. *there are a few slow yellow ones out there, i've seen them.
however, in 1980-1983, they dropped the hobbit name and are all called PA50. They are all PA50-II spec, meaning the 30mph FAST stock version. Always check the year.
If you are worried because you own a RED 78-79, dont fret. You just need a PA50-II reedblock, intake and carb.. cylinder (unless you're throwin on a kit!) and the outermost variator ramp plate to make it PA50-II spec. you'll need to dremel out that plate a little bit so it can slide on but thats no big deal. Or, PA50-II complete motors are common on ebay and sell for less than $100 usually. Watch out for the variator weight guides.. they are made out of plastic and frequently break, making the variator weights unable to open all the way therefore not hitting top speed.
There is a massive aftermarket following for Honda Caminos (same thing) in Europe, lots of fun videos to watch on Youtube. caminotuning.be is a cool site if you love to read through translators.. Hobbits and Caminos are from Belgium, not Japan!
Hobbits are naturally VERY powerful.. with a Proma Circuit ($110 @ TreatsHQ) you'll have a bolt on 8 mph increase, with no jetting change nessesary. This makes your hobbit a legit 36-38 mph with just a bolt on pipe. Then buy a kit, upjet to a 90 and have a legit 45mph bike that RIPS up to speed. Mod the variator walls and get another 10mph. Get some reeds and have some better throttle response and midrange. All of this on the stock carb. A new carb wont give you any more top speed unless you're into some level 8 or 9 shit, with a motomatic pipe ya know?
55 redonkulously reliable mph for under $300. Bonus.
Many people have told me that riding a hobbit is like riding nothing else. The level of whimsy and speed and smoothness and fun is unrivaled by any other ped and i agree. Plus, they are cheap as fuck to make fast and are by far the most reliable of all peds that i can think of. its a honda!
