Technical Question - Suspension

Post by jamesn »

Hi there

Im not sure if this is the correct place to ask technical questions but I couldn't seem to find a better place to ask a question so here goes!

I have a CBR1000RR which as previously stated I love to ride but I think It would benefit from a performance upgrade.

Do any of you have any recommendations of how I can improve performance?

Many thanks, all comments appreciated.

How old is the bike and how many miles?

What sort of thing are you looking for and is it for the road or the track?

Have you done simple things like servicing the fork oil? Made a massive difference on my RSV as I had let it slip for a number of years.

Suspension, suspension and suspension. In that order would be my recommendation regardless of track or road use. Even if it's just refreshing what you've got.

Get it serviced and then set up for your weight and use by an expert. Best use of money you will spend on a bike.

What year Blade ?

Where do you think it is under performing ? Will help target the correct mods. Try and be specific don't just say suspension. Help with a little more detail. For example dives on the brakes, rebounds quickly coming off the brakes, back squats down etc.....

This is the guy I use, and his own bike is a CBR1000. Can't recommend him enough, plus extremely reasonable prices.

Good guy but plenty you can do yourself first and save a few quid depending on age, model and mileage.

Hi again, thanks for all your helpful replies, my bike is a 2013 and is used for road use occasional track day. I managed to speak to a suspension company that I found on the internet, one of my work colleagues also recommended them, http://www.brooksuspension.co.uk/" onclick="window.open(this.href);return false; I called them up and they recommended refreshing both front and rear suspension with fresh oil and seals etc. The guy I spoke to also mentioned putting new fork springs in to suit my weight, he said I should see a big improvement just by doing this. Im going to book them in with him in the next few weeks, I will let you know how it goes on.

If you're getting that done then it's probably worth getting the rear spring swapped over as well. You can have one sorted for your riding weight and style.

I need to get my front forks refreshed.

Typically the rear suspension is the weak link on Japanese bikes. I'd be surprised if a fork/shock refresh made any noticeable difference without changing the springs as the oil is still pretty new and probably not had a great deal of hard use.

Next time you do a trackday, go to the suspension guy and ask him to help you set your bike up through the day. It will cost between £20 and £50 most likely but you will definitely find it beneficial

Great, thanks for the info. When I spoke to Brooks they mentioned they could spring rate test the springs to see if they are suitable for my weight, I will get him to do both ends and see how I get on!

No the problem is the oil the OEMs use, this should be replaced every 2 years. Better quality oil can last a lot longer

Are you taking the parts off the bike or leaving the bike with them?

I think K tech have disappeared up their own backside of late. They only do their own rear shocks which are about £1,200.
