boardtrack bike gets a motor

i just temp installed the motor, oil cooler and foot pegs. still need to add an upper motor mount and finish weld/ trim everything still

The board track bike is a roller

finally got the board track bike into "roller" status. this thing has a mean stance.

more on the board track

i finally got enough strength back in my hand to use my tube bender so its back to the boardtrack bike build. i welded on the top of the rear frame section today. everything is still just tacked in place. once i get the motor mounts aligned and welded on i will finish weld the frame. the frame is leaning fwd on the frame jig in the bottom picture. when finished the bottom tube of the bike will sit parallel with the ground.

headlight

here is the headlight i will be using on the board track bike. not really sure where it came from.  Its a nice piece, it just needs a bit of repair.

wheels

here are the wheels and tires i will be using for the build as well as the axle plate measurements for worksman wheels (as requested by a few people)

what what in the butt

I started fabing up the rear of the board track bike yesterday. The motor is only sitting on the frame for a clearance check and the dirty old bike tire is just for reference.

front forks from scratch

Here are the forks i made for the board track bike. They still need to be finish welded and i need to fab the handle bar/ upper suspension mount. i know there are some other builders building similar suspension setups but this is my own design. Pretty much all my work proves that you dont have to have expensive equipment to build cool stuff.

Board track bike wheels

Here is the rear wheel for the board track bike. they are custom built clincher wheels with 10 gauge stainless spokes laced to worksman front drum hubs. i drilled out one of the hubs for a sprocket adapter then milled out an adapter out of 1/2'' 6061 aluminum plate. the sprocket is a 40 tooth pitbike sprocket.

board track forks

At the moment i am building the front suspension for the board track bike. The wheel pictured is only for mock up. I am using motorcycle wheels on the finished bike.

board track build start

I recently started the board track build. It is for someone who wants the ride-ability of a scooter and not having to register or insure their ride. Also he did not want to be seen riding a scooter. It is running board track style motorcycle rims and tires. the engine is a pitster pro 140cc race engine which actually puts out more HP then some board track racing era production 1000cc v-twins. i know this bike will probably get hated on alot because of my engine choice but for the price you cant beat it and its damn fun so if you don't like it, fuck off and go buy some more chrome for your Harley.

the engine

this is going to be the engine for the boardtrack build. it is a pitster pro 140cc crate engine. for the power you cant beat the price. i have not seen any exact HP specs but it is estimated to put out around 10 to 14 hp in stock form.

inspiration

i am still ordering the parts to start my board track inspired build but in the mean time here are some pictures that inspired me

scooters are gay

lets face it scooters/mopeds are gay and often compared to fat chicks.

 although the idea of riding a moped is quickly dismissed by most, building a motorbike of 50 cc's or less opens many possibilities. for instance in Nevada you do not have to register or ensure a motor vehicle of 50 cc's or less. you dont even have to wear a helmet!
      Now here is my idea and what i am in the process of building for a client. i am building a motorbike based on the 1914 Harley

but with this engine

this is a honda XR50 engine. there are many clones out there that can be had for less then $300.00 brand new. why this motor you ask? well in stock form it is just shy of 50cc's and makes somewhere around 2 to 5 hp but many performance parts are available for this motor. big bore kits are under $100.00 in most cases. with the right parts and tuning 13 to 15 hp is very possible and would propel a motorbike with this motor well over 60mph. there is allot going into this build to make it safe. i am by no means slapping this motor into a bicycle frame and going 70mph. everything will be purpose built to handle the speed. check back for the progress.
