Will Jacking Up My Bike Resolve My Cornering Problems

[Az]

So, I know the popular response is, it ruins your handling.

But here's my problem…

I'm far from a heavy guy (weigh around 60kg/65kg) so i'm hardly suppressing my suspension, but every time I take a decent left bend I scrape my left boot when my foot is tucked under the gear lever and no, I don't have big feet (size 8).

I'm pretty much cranking the bike as far over as I can and occasionally I will get a peg scrape if I put my toes on my foot peg rather than my heel and i'm still not using all of my tyre, which is clear by looking at my tyre as I still have chicken strips
(pictures of both sides of my tyre below)

Will jacking up my bike allow me to use more of my tyre and get lower without scraping the pegs ? Also jacking up my bike will obviously get rid of this foot dragging problem (which I don't like).

TL;DR: On most decent left bends my foot or pegs catch the floor, will I be better off jacking up the bike, or are the negatives of having the standard dog bones/seat height not as bad as the negatives of jacking up the bike by 30mm.

Just to add as well, when I sit on the bike the suspension does suppress a bit. Is it possible that my rear shock is shot and that it's causing the bike to ride lower, therefore the pegs are closer to the ground than they should be making it easier for them to touch the ground.

If this is the case, how can I tell if my shock needs refurbishing or replacing?

Your phone is bad and you should feel bad.

Is the suspension setup for you or are the settings the same as what they were when you bought it? Do you know if the suspension has ever been serviced?

Are you scrapping your right peg or just the left?

hang off more.

Fixing your foot position as G says should make loads of difference then hanging off more like MarJay says will mean you're leaning the bike less in corners.

For suspension settings I'd suggest asking on a Blandit forum cos they'll know more about your bike than the collective mind of BCF does.

MarJay wrote a thread about suspension setup way back in 2004 which should help you have a better understanding of how to adjust your suspension. https://www.bikechatforums.com/viewtopic.php?p=1050226

You seem to have mould spikes sticking off of your tyre = pussy....

My chicken strips are about 1/2 an inch wide....

Am I the only one here that does not give a shit if I do not use the outside edge of my tyre and have "chicken strips?" I still get around the corner, I even manage it at a decent speed.

I dont see what the fuss is about really.

I used to rag my bandit like fuck around bends. I'd have pegs scraping out, be hanging off like an ape etc.

I still had about half inch of chicken strips. I'd say it's more the bike than you tbh. I had massive chicken strips when I had a 180 on the rear as the edges were almost vertical

It's the bike not you. They aren't built for it, the more you get used to it the more you'll realise. Biggest weak point for me was the wallowy suspension even with progressive springs and thicker oil.

Another 20bhp wouldn't have gone amiss either

I scrape my foot on the pan euro if i've not got the ball of my foot on the pegs, sometimes the pegs go down, it's not a sports bike, it just the way it is.

I agree with the hanging off more and balls of your feet on the peg.

But I also think it's down to the bike also. Below is a pic of my recent trackday on my Honda CBR 600 F.

Peg and toe was scraping, I was hanging off correctly and feet in the right place. I think I'm in need of adjustable rearsets so the peg can be moved so I can lean it more - I may be wrong but that's what I thought

I increased the preload on my SH300 from the minimum (1 of 5) to medium (3 of 5) to avoid the centrestand scraping as easily when cornering. I, also, weigh around 60kg.

The centerstand on it also starts scraping at around 6mm left on the edge of the tyre. However, I won't jack it up any more, not because of handling exactly, but because the suspension would have less leeway to track hollows in the ground.

There's two forces affecting the suspension when cornering smoothly on flat ground, besides the gravity that affects it when upright. Centrifugal forces load the suspension, and acceleration unloads it. If you're cornering while still decelerating, the rear is allowed to squat more than if you're accelerating.

Hard acceleration wants to lift the bike into a wheelie. That is, the rear tyre is trying to rotate the rest of the bike upwards via the chain, using the swingarm axle as a pivot. That's why acceleration usually unloads the rear suspension, despite weight transfer putting more weight on it.

tl;dr: accelerating through the corner will give you more leeway to use your tyre. Don't go crazy though.

As the seat is above the pegs on a bandit/CBR, it should have a similar height change whichever end you do.
If you had cruiser 'highway pegs', then sure, lifting the rear wouldn't do so much for foot pegs.
Normally I'd advise matching the front and rear for raising/lowering, but for track work you often want quicker turning, which would mean a lower attitude - so raising the rear would make sense.
I would expect raising the rear would affect the pegs more than doing the front.

C Spanner means pre load. Pre load should be set based on "sag" - it's likely if you're light that yours ma be a bit high already.
