Default Adult on CRF80.....

     

Hey all, I'm new here. I rip around on a 2004 CRF80. I spend most my time on a guitar forum actually, were it's members come down hard on newbies for asking any question where the obvious answer is... "Use the search tool!!" Which I will in a moment. But, in the meantime. My question is. Has any of you 200lb'ers put heavier springs on your CRF80 and been 'happy' with the results?

I have some land and have built a track. It's not HUGE. Maybe 300x200' but it has a couple some respectable jumps for a 42yo guy on an 80. @ 20' doubles and table tops. And growing as I get more comfortable. As long as I nail the landings, there's no issues at all. I'd would only bottom if I over/under jumped it, and it can be a bit harsh. I found a place with "30% stiffer than stock" springs. I guess that would be ok. Not sure yet.

opinions.... I'm quite satisfied with the bike otherwise, so I'm not replacing it. And I don't want a bigger bike. The whole reason to going small bike is to ride a small bike. Less temptation to build 50' to 70' doubles. I used to race a bit on a KX250. But that was some years ago.

I'm sure I'm beating a dead horse with this thread. But, that's what us guys new to a forum do.

Thanks, Darin

hmmmmm, 200 lbs on a 80?? I think if you're hell bent on riding it, leave it like it is, I really don't think you're going to tune the suspension to handle your weight.. But that's just MHO..

I have a 2006 CRF80f I ride some. I just set the rear spring as tight as it will go and ride it. I'm 215#. I dont jump it though, Mostly woods. Its a great little bike to ride. I really would like to put some bar risers on it so my knees dont hit the bars.

I'm 100% positive that if you were to put stiffer fork and shock springs in that CRF 80 that you'll be waay happier with it. I've got a CRF 50 with a BBR stiffer shock spring in the rear and it really made a difference. I also have friends who have stiffer fork springs from BBR and it really does harden up the front end.

I suggest looking into BBR Motorsports, they have TONS of stuff for mini's

Welcome to the site!!
I suppose I am "bent" on riding it. It's the right size for my track. It's not so fast that I'm tempted to go very fast. Yet it's plenty fast enough for ripping through the loamy berms and clearing a 20' double. Which I know is a absolutely nothing on a 250. I raced BMX Cruiser class a few years ago. And this is alot faster, and the jumps are a lot bigger. It's fast enough to get hurt, so it's still challenging enough, the jumps are still big enough that you don't want to case the landing, or over jump it. And the landings are just a tad bigger than the bike itself on a few of the doubles. So nailing them is essential. The 1 big jump, that grows by the day, is big enough that it fun, and the landing is pretty long so there's plenty room for error. The big one started as a table top at about 17'. Now it's 20 or so from top to top, and I remove dirt from the middle and add to the landing each day. I'll probably stop before I hit 30'. Though, I come too close to hitting the flat now. So 30' will be about the limit anyway. Still, with bone stock bike. I'm really pretty ok. There's enough low end power with it being a 4 stoke that I don't fan the clutch like I would on a CR. The other plus to this bike is. The neighbors don't scream at me. I have no intention of making it faster, or louder. Unless I'm hitting the top speed in top gear, I don't need any more than I have. I am getting used to riding a 4 stroke though. It responded differently to revving and fanning the clutch than a 2 stroke. Even when it sounds a bit "bogged" it's still making power, unlike a 2 stroke.

Riding a "mini" is fun, challenging, fast enough, and keep me out of trouble. So, I'll keep riding the 80 for all the same reasons you ride a 250. From my couch to the track is about 100'. Throw on the boots, the helmet, do a few laps, then come back in and chill for a bit. Not so bad really.

little minis are cool. And those 80's rip pretty good. I had a 125 Xtreme pit bike. The bike was a lot smaller than your 80. I'm 200+ as well and I had more fun on that bike than I do on my 450. I don't think you will gain much with a heavy spring, but if your "bent" on changing it out, go for it. No doubt those little bikes are fun. Wish I still had mine.

That is a splendid idea. It rained today, so a couple days of dry time will be in order. I hate the rain, but at least after 2 days, the dirt is perfect. Especially for shovel duty.

I hope I did not offend you with my last post (none meant) I was just trying to say that you are not going to make an 80 handle like a bigger bike, it is what it is.... I was riding my sons XR 80 this weekend and having a blast, but I don't expect it to handle like my YZ....

No offense taken.
I know my 80 ain't going to ride like a 250. But it would be nice if I had a bit more stiffness. At least i think it would be. It's not alot of travel, but I'm using it all and not really bottoming unless I take a jump to a FLAT landing. Even then, if I land one wheel first, it's less an issue. My biggest jump a double is something like 4 feet high and 20 feet across. It was a table top. I'm diggin out the middle a little each day I ride and add the dirt to the landing to extend the jump. Since I'm probably getting an additional 4 feet of height, I certainly do not want to over jump. Occasionally I'll get my front wheel to the very bottom of the 10 foot or so long landing ramp. It doesn't take much effort to go from hitting the center of the landing to the bottom. I'm sure that a flat landing is bound to happen eventually. The other jumps aren't very high, they are both doubles about 13 to 15 feet, but the landing ramps are no longer than the bike itself. I usually clip the top with the back wheel. Still, it's not a rough landing, but I think a bit more cushion would take some of the fatigue off.

Ok, some pics.



















My "big 20'er"!











Laugh all you want. It's small. It's "mini" if you will. But it's a blast, and it's right out my back door. Everything is scaled down and just right for "big guy on 80" riding.

I said something rather silly in an earlier post. I need stiffer suspension on my 80 in case I case a jump.... duh!

Looks to me like you're having fun...

and that's really all that matters!

Cool track, I'd love to have a yard big enough for something like that.

Here's the scoop. I'm thinking of "upgrading". I don't want to go to a "full sized" bike. My track just doesn't warrant it. I really enjoy riding the 2004 crf80. My concern is that it is physically small, and perhaps not meant for a 215bl guy doing 20 doubles. I saw today a bike that made me drool. A CRF150. Bit pricey for a new one. But I'm strongly leaning toward it. Anyone ride one of these things?
