will other bike forks fit my bike???

[SP1K3_BPsy_1st9]

Probably a stupid question but does anyone know if any forks will fit my bit, it's a Yamaha SRX 400. i'm thinking about putting yzf-r6 forks on but im not sure if they will fit.
Can anyone help?

Please stop using a massive bold font! there is no need to try to grab our attention when we're already in your thread.

The SRX600 i should imagine has the same forks but it's certainly worth checking. Having only owned one of them i can only give you info about them. The early ones had 36mm diameter fork, the later ones 38mm. The 36mm ones are the same as the ones used in the pre diversion XJ 600 (often called the FJ600), i know cause i had both at once

The R6 will be running about 43mm forks. So you'd have to modify some R6 or similar yokes to fit the SRX frame. You'd have to checkt he length of the forks too and drop them through the yokes / find some magical way of lengthening them. Then you'd have to check the space between the forks to see how much wider they are and make some spacers to go either side of the front wheel. The front wheel might well need machining out to take an R6 wheel bearing. The brake caliper mounts would need to be adapted.
An easier solution would be to use the R6 front wheel assembly too.

Front end parts like forks and front wheels for sports bikes are notoriously difficult / expensive as people don't generally break up non crashed bikes. This leaves the parts supply limited to those that have crashed and as they tend to be travelling forwards when they do so the fronts are usually the first bits to be wrecked.

If you did the above and got the R6 forks on it, what would you hope to be gaining?
Making it look faster? You could buy a much faster bike with the money all of the above is going to cost you.
Making it handle better? The geometry will still be from the SRX, the wheel base and head angle will all be unchanged. The new forks will have springs designed for dealing with slamming on the brakes at 170mph, they'll be way too firm for the SRX which is one of the lightest bikes i've ever ridden.

The SRX is a bit of a classic. Sticking R6 forks on it is a bit like putting lexus lights on an E-type jag.

Ultimately i think this is what you're looking for:

Anything will fit, it's just how much work you have to do that makes the difference

You need to check but I think your fork tubes are 36mm and the Yamaha are 43mm so it isn't going to be a straight swap. There are very few modern bikes, other than motocross and something like the XV535, that use a 36mm diameter.
You might be able to swap the complete front end but it is very likely that you will have to do some modifications to the stem to get it to fit your headstock. You will also need to check the overall lengths to ensure that you aren't changing the geometry significantly.

Why do you want to change it? Looks like it is going to get expensive and take a fair bit of work to get them to fit.

i don't mind changing the yokes do they make a difference?

and marki cheers that some list with some good ideas for doner bikes

[Ichy]

Changing the yokes may not be straight forward. The stem needs to match the head on the frame. You can sometime get around this by fitting different bearings or machining the stem. You then have to consider the width of the forks for wheel spacing etc. This is why it is usually easier to just change the complete front end.

Still the same question though, why? You aren't looking at improving the handling so it must be cosmetic. Is it worth the cost?

A good few years ago I had a RD250LC fitted with FZR600 forks and swing arm, really looked the dogs wotsits and rode well.

Have a read of this months Practical Sportsbike magazine. A guy has built a highly sexual looking SRX600 special with bits from modern sportsbikes, and plenty of custom fab work as well.

The forks used were Hayabusa, with GSXR K5 Yokes I think. The front wheel was a hub from an XTZ660X with a 17'' rim laced up to it. The rear wheel was also XTZ660X based.

I don't think he had the forks re-valved to suit the SRX, and he was using a single 320mm disc and a 6pot Tockio caliper.

The bike looks the absolute dogs dongler IMO too!

[SP1K3_BPsy_1st9]

cheers fir the help gents but ive had a change of heart as the missus found me a set of rather sexual wheels online that will fit my bike so im just going to overhaul my forks and paint them
