Max Rider Weight for a YZ 85

Recommended Posts

I'm 40 years old and have a CRF 450. Don't ride but twice a month and would like to get a two stroke. One of my buddies who is about my size (5'8" 165lbs) got a CR 85 and rode it like he stole it for a couple years, then traded up for a 125. I'm thinking I might like to do the same thing just because I think I'd have a lot more fun riding something a little more manageable. I might go up to 170 over the next year. What suspension modifications will I need to make, and how much of a pounding will the engine take pulling me around? I've owned my CRF since "03" and I've rebuilt it from the bottom up twice and I really enjoy maintenance / wrenching. Thoughts or guidance?

Honestly I think you would be better off with a 125 right off the bat. I had a yz80 about 7 years ago and just purchased a 125 last year. It was a little intimidating at first but after about 2 rides i felt in complete control. You wouldn't really have to do anything to the 125's suspension and it gives a little room to grow. When I got rid of my 80 I was about your height and weight and it was starting to get really frustrating to ride because i had to constantly keep it on the pipe or it would stall so easily, there is no room to lug it. With the 125 I have some lug room but also can keep it on the pipe too.

The 125 would probably be your better bet but Im 180 and can jump 85's like those crazy little kids. Its much easier to pin it wide open around a corner, only thing is it would be much more unforgiving if you come up short which can happen pretty easily.

I ride my wife's 06 yz85 all the time now, since my 250 isn't running yet. They are a blast to ride! I love the power! (top end power) I ride that thing at least twice a week and I weigh 190. It pulls me everywhere on the back wheel no problem. Just watch the bottom and mid range, there is none. I find it more fun to ride than a 125. The 85 acually hits harder at the powerband, or that is what it feels like, it goes from 5 hp to 20 hp instantly.

a 125 is a great beginner bike, and still a great bike even after you polish your skills.

an 80 or 85 is more of a play bike you take to the track to just goof off on and isn't something you'll want to keep riding for the next few years.

+1 on riding the 85. I rode the 85 I bought for my nephew and couldn't stop smiling until I bent the bars. I way 190 and the suspension is completely inadequate but it was SOO MUCH FUN. I'd really like to put stiffer springs on it and use it as a mini moto bike. Instead of taking a CRF50 and dropping $10k into it, just pick up an 85 and put stiffer springs on it and your ready to ride.

Am I looking at a typo here?

You have a 450 and you are thinking of going to an 85 or 125?

Get a 250 two stroke and learn to tune it to your liking.

No matter what I do to my 250 I could never ride it like an 85. So theres always a good reason for the change.

Man, you give up so much on a smaller wheeled bike, especially off road. I wouldn't do it. 85's are fun, but a full size bike with more manageable power is what you are looking for, if I'm reading your post right. I'd go with a 125 or a 250f.

Besides if you went with an 85 you actually have to shift... :-)

Between myself, my wife and our kids we have 6 bikes in the garage from a CRF50 to a race modded RMZ450. The bike that's the most fun and makes me feel like a little kid again is the 2016 KTM 65sx. I started riding it so I could cruise around with my stepson on his 50 at the local jr track. I was amazed!!! Crazy power, I mean CRAZY and super fun for play riding. So much so I had to buy my stepson a KLX 110 for his next bike because he wasn't ready for the 65 in full race mode. That being said the cockpit is a little cramped, everything gets seat bounced because there is no standing up and at 195lbs the suspension has a nervous breakdown if I don't grease the jumps perfect. This is a 65 I'm talking about after all. I'm sure an 85 would be a little more comfortable and have a lot stiffer spring options available than a 65. I haven't messed with the spring rates because this bike is supposed to be for the kids. I would go for a late model KTM or Husky if I was going to get an 85. They are light years ahead of the Japanese 85s.

I have a '18 yz250x and a '21 crf250r. Those bikes are fun to ride, but they pale in comparison to the fun I have on my CR85 pit bike. I have bar risers and bbr stiffer springs on it. Once their sprung right they're great.
