Rokon Tech Tips: Triangle Thingy (Rear sprocket chain guard)

[@officerkrumpkie]

Yes! More Rokon vids please. Thanks

[@letharius730]

I have never even heard of a Rokon before. I have to say im impressed by what that lil thing can do for only weighing 200lbs. I kinda want one now. lol

[@jayknight850]

Good presentation on an very interesting bike.

[@backwoods6050]

NAPA sells large, very heavy duty, mud flaps that are about 1/4" thick for $10. I cut mine to size on a bandsaw, but you could use a jig saw as well. Forget about cutting it with tin snips.

I'm in the process of putting one my bike right now, thanks Mark. I like the Ravi Shankar music.

[@markmcdonald6653]

Mark and Bob this was very thought provoking and informative. I'm glad you did this on as I don't have one on my 69 that I'm rebuilding. I'll have to make sure this is done. BTW You do know you just added to the Rokon lexicon with "triangle thingy" :)

[@Firemountainoutdoorsreviews]

If you own a Rokon... Do you still have your Triangle Thingy? It's crucial. Check out the video.

[@northman77]

That is brilliant! I already broke many mountain bike this way... I will do this on the motorbike as well.

[@spyke123able]

I believe it's called a chain guard!

[@SLFYSH]

Very important tech tip! -but on most motorcycles what to call this is already solved. It's called a lower chain guard.

[@Firemountainoutdoorsreviews]

Triangle thingy has a certain ring to it...

[@SLFYSH]

Yup. But either way it seems like such a simple fix to an unnecessary and potentially catastrophic problem. Thank you. Another question, I've been looking for a Rokon to buy, and in my shopping Ive seen a couple for sale which had unusually even higher prices, stating a number of repairs of mechanical flaws and weaknesses, some of which related to somehow beefing up the front miter box, and the drive shaft from rear to front? Do you know anything about this? I've love to see fixes for common problems.

Hi Mark, I just recently purchased an early 70's Rokon Trail-Breaker like Bob's, and it has the same gap in the rear Miter Box. Should I address that ? Has Bob done anything to repair his Rokon, or does he continue to ride it with that gap?

[@avandervest]

It's not bent the sprocket on the right is smaller than the one on the left. If you notice the chain on the right is the same size as the housing while the chain sprocket is larger than the housing on the left. At 1:45 look across from the left chain to the right chain

[@Scottchmorsco]

Great info.

[@MasterSumai]

Would it be feasible to strengthen that Rear Miter Box Tab to the frame somehow?

[@chuatigris9858]

The black rokon has been modified for street use?

[@bradleyhajost7161]

Thank you!

[@getprobed838]

What is that third bike thats not a Rokon? The silver one. I see its 2x2 but I dont know what it is.

[@LACARRINDANGA]

Hi. can you tell me the diameter of the pipe used in the frame (under the engine) and in the fork ? ill appretiate it so much. Regards from Argentina

[@heartland96a]

What of using conveyor belting from TSC? They also have horse stall mats made of thick rubber?

[@markpinther9296]

You mentioned building your own Rokon. Did you end up fabricating your own frame and building a 2x2 similar to a Rokon? I'm asking because I would like to do the same.

[@brianatherton4916]

I have an old trailbreaker I put a liquid cooled XZ 125 engine in.

[@trevorzzealley2670]

Your test ground looked a bit like Hancocks Plantations front yard ,well known for eating mechanical stuff.

[@robertlangley258]

How bout, Rear Tire Chain Guard?

[@jacobsebastien3910]

Sticks can go Behind the rubber gaurd..

[@robbie574]

Nice bike Bob!! Too bad about that ugly sticker :)

[@johnjriggsarchery2457]

Funny coincidence: I was going through a deep trench of mud several days ago, caught a stick and threw the chain.

[@hibobb123456]

Try saying "rearward" (2:13, 2:15, & 2:19) three times fast....

[@bobdudley9806]

Backwards

[@stevelevesque3274]

[@craigmarine7564]

I have a tech tip, use american parts and machinery

[@MasterSumai]

Rokons are made in the USA since 1958.
