Topic: I've got an 83' Honda XR100 'playbike' & looking for fork springs

[grcamna2]

I have this little 83' XR100 playbike and I want to put a set of aftermarket fork springs on it so that my 235lb self can ride it w/o bottoming the forks all the time;it has 27mm O.D. fork tubes with the stock fork springs which have had spacers installed in them to compensate & that helps somewhat.. They upgraded the forks on the 1985'+ XR100's and those springs won't fit my 83'.
I called Progressive Suspension,they didn't have them that small,so now I'm at a loss and wondered if there's some place that sells stuff for small playbikes and would have a listing for my 83' XR100 for a pr. of stronger fork springs.
A fellow told me BBR makes them,not sure if they'll be heavy enough?

Hi,I called them and they said they don't make them that small(17.5mm O.D.)of diameter.

Hi, I'd like to see some pics of this bike......sounds like a neat bike.

Also, you could try a heavier fork oil to stiffen them up.

I've got a CB100, that I play in the back yard, to bruise ribs, when a little tipsy. (drunk)

I'm also rebuilding a CL100, haven't really figured out the type of final outcome. Maybe a town runner. Nothing crazy, I think.

Drill and tap the fork caps for Schrader valves, and pump about 15 PSI into them; my '82 Honda CR 480 and '82 Honda FT Ascot both came with air valves in the caps from the factory.

[Alan F.]

True. My CM400C had caps and a balance tube, spec was 3-11psi, so 1.5-5.5 per side?

[grcamna2]

I used to use air but found it causes a bit of stiction in the forks where they don't move as smoothly on my road bike.I have put-in up to 5 lbs. without a problem though.

Add distances inside to stiffen them up.

Yes,I have some spacers in there.

[dave500]

im with heavier oil,cheapest easiest thing to try.

[grcamna2]

I just ordered a set of fork springs that member here 'Alan F.' told me about;he must have had to do a bunch of searching to find them.They were on the Kmart website no less !  The dimensions to fit my application match and the price was great with free shipping. 

[Alan F.]

They came up in a search for 17.5mm fork springs. I think K-mart is only online now and they'll sell you anything they can get their hands on just like WalMart.com.

I'd still like to see the bike.........

I want to install heavier fork springs on two bikes.
The one XR100 I haven't actually taken possession of it yet but will be when I finish paying a friend for it.
The 81' CB125S which has the XR200R engine and front disc brake needs better springs also.
The bottom picture shows the bike w/o footpegs;I had just reinstalled the 185 engine and it was before I bolted them up.

After finishing a few old projects I'll be doing a steering stem swap to add CB400T 33mm forks to a 250 Nigthawk. It's got a 310mm? drum now but I'll swap out the left fork lower for one from a CX500 so I can run the single disc & twin piston caliper with a pair of tubeless Comstars, I'll probably toss in some cheap cartridge emulators and look around at springs too.

What are those rear shocks Bill?

Hi Alan,that's a good thing,going over to disc:drum fronts just won't cut-it.
The rear shocks on this little 'mini-bike'  are very cheap(purchased from Wemoto UK $130 shipped)YSS shocks(13" eye to eye)made to fit a UK version CB125RS;they're a hair better in quality than OEM which were worn out.I prefer a better quality shock with what I carry on this bike,max load is 325lbs. & the rack will carry 65lbs+.This is my daily rider and a real workhorse,it even rolls on Interstates with me tucked out of the wind blasts.
I'm installing a black XR low miles dirt bike engine,fully rebuilt with more power this weekend;my powersports machinist did a Great job on cutting the valve seats for maximum flow.

[Alan F.]

That's a lot of weight for a rear rack! Make sure to check it for cracks now and then.

Wow.....nice. Like that rack.
