Turning under brakes.

[Spac]

Not strictly a suspension question, more a handling one.

2019 Beta 200RR. Older Marzocchi CC forks, with ~0.45 springs, Ohlins TTX Flow shock with 5.6 spring. Starcross 5 Mediums on both ends. 90/100 front, 100/100 rear.

Overall I am VERY happy with it - definitely the best handling, best suspended bike I have ridden.

But I have discovered a behaviour that I have not experienced before and am wondering what causes it.

We were on some beautiful, smooth, flowing single track on the weekend. Amazing traction. It was pretty much trail riding heaven, really. Of course, I wound my pace up and had a bit of a go.

Occasionally a corner was a tighter than I expected and I would still be hard under brakes as I turned in. At this point, the bike would suddenly feel very heavy and the steering was very stiff. Locking the rear brake didn’t change it.

I have never experienced this on anything before. It was entirely possible to muscle it through, but it was an odd feeling.
It didn’t happen any other time - less traction, lighter braking, riding slower, setting up for the corner properly, whatever, I couldn’t replicate it - it only happened when I was pushing and traction was way better than usual.

Any thoughts? It is completely outside of my experience, so I don’t even know whether it is actually a problem or just something that happens when everything is working really well.

You probably had a wombat caught between front gaurd and tyre ...


On cusp of dynamic forces .

Consider rear slide steering ,,,with rear tyre locked up , it's very very effective , for tight stuff once u master it


can load the rear when coming to Aimpoint , often near to upright and apply power ,

In a gear high if you've carried enuff pace .....

close your eyes and tip it in harder

I’m no expert- But I do ran the same front tyre S5 SOFT 90-100, being a larger tyre isn’t the best tyre for FAST corners & your narrow rear 100-100-18 is a odd combination. A 80-100-21 front with a 100-100-18 rear would turn a lot faster and sharp. Just my thoughts.

Yeah. I usually run 90/100 front and 110/100 rear on 200s, but the smaller rear was just to get a bit more life from an old mousse. It feels absolutely fine in every other circumstance, so I am not thinking that it is related to this issue.

Sounds like the front is very planted , happens to me when braking hard into a rut or front traction is good , like all the braking force and weight is on the front end , i tend to counter that with sitting and getting the weight back over the rear , lets you punch it out of the corner knowing the front will still hang on , thats how i deal with it on the Gasser.

Called front grip. Normally a front tyre will under steer or oversteer depending on tyre, grip, speed angle etc. seems like it was just prime and perfect. JMI anyhow, think of the difference between a front end tucking, and sliding out. Just ride it

I think I've felt the front end heaviness on my ktm200, but it is usually when a corner catches me off guard and I loose my attack-position/mindset or something like that.
