Front End conversions

[Blue_SV650S]

Ok so I did a search, seems people are doing them from various different donor bikes, GSXR600s, 750s, thous. Some mixing and matching all sorts of stuff off different bikes. \:D/

But it’s all a little too complex!!! #-o Has anyone just bolted a complete front end off a bike straight on, no messing?!?!

Or has anyone bolted a front end off a different manufactures bike, like an R1, or R6, CBR600RR etc …

I was going to keep an eye out on eBay to see if I could get a complete front end (forks, yokes, wheel, callipers etc) off any modern sports 600-1000 really, and just bolt it on!!

If buying a complete front like this, the only thing I can see stopping me is that if the distance between yokes is different and that the stem is the wrong size/has the wrong size bearings.

Soooooo … in summery, which bikes front ends slot straight in? Anyone done a conversion from a non Suzuki donor? If so what bike?

Anyone guess what I have in mind!!?!? :)

On your bike, GSXR SRAD 600 or 750 very nearly bolts right in- just wants a different top bearing, which are available easily. (I used Twin Works Factory in the states, I think JHS does one, as do the SV Race Shop) If you want the parking lock to work, 10 minutes with a grinder or dremel is sometimes needed, the rest is bolt-on- even the lock stops fit.

You can get any front to fit... it just depends on how much work you are prepared to do.

Cheers northwind, the old SRAD stuff should be pretty plentiful by now too … just hard to find straight stuff!!! :? Is there any difference between the 750 setup and the 600??? Were the SRAD 750s USD?

Grinch … I think it is safe to assume from my post that I don’t want any faffing!!! :D

You could pay someone to faff...

[northwind]

No real need though. The SRAD bits are good quality (though as you say, old) and look right on the bike too- the SRAD wheel is the same as the carbed SV rear and even comes in the same colours. SRAD 600 is RWU, SRAD 750 is USD.

Really it's the SRAD yokes that are the gift. You can put other 50mm forks into them, for example the Y-K3 forks I've used are in a SRAD yoke, with a SRAD axle and wheel but K2 mudguard and calipers. No great benefit to that, mind, the forks are very similiar, but good K2 ones are easier to find. I think the same goes for K1 and K2 thou forks, but they're (apparently) less good. Though shiny.

It's only when you start playing with radials that things get more complicated. I don't see much benefit to the forks, but Ben reckons the forks are way better (Max Macallister at Traxxion has said that the K6 750 showas are the first road bike forks he's ever found that he'd be happy to put on a race bike unmodified)

Grinch - PAY someone to faff … PAY … :D … I love to faff myself, so would never dream of PAYING someone else to do so …

I use this bike every day, therefore don’t have the luxury of prolonged downtime. A weekend would be max, hence the desire of a direct swap solution.

Northwind – thanks for the info, I know what to look out for now, cheers :)

One point of confusion though presumably the 750 and the 600 yokes are different if one is USD? Or are they both 50mm?

[TSM]

RWU or SRAD 600 yokes are 45mm
USD or SRAD 750 yokes are 50mm (i dont know if the bottom yoke is diffrent to the top)

[northwind]

Good catch, I meant to say SRAD 750.

The bars are a little low with the SRAD yokes, is one of the drawbacks. Not an awful lot of clearance between clipons and fairings, I found my throttle cable dragged on the plastics. With the USD forks, TL1000S clipons are a little taller and prevent this (as well as taking some weight off your wrists).

Very nice, get you mudguard colour coded, just have done mine really blends in all in and makes it look more stock than a black one.

[fearless ferret]

got a piccy?

got a piccy?

Will post one tomorrow

Just wondering but can you fit a top yoke to allow Renthals so the forks could be fitted to a nekkid machine? :?

Its called a drill...

Here, I had a little thought after the ‘the yokes are the gift’ comment ….

To presumably reduce cost and complexity, isn’t it going to be easiest just to find some sports bike forks that have the same diameter fork tubes/stanchions so they can fit in the standard yokes, rather than replace the whole lot??

Now here is the tricky bit … firstly what dia are the SV forks? (I can measure, but if someone already knows … ) and what (if any) sports bike shares the same dia fork tubes?!?! <crosses fingers> Please be something good … please be something good!! :)

Well there are lots of RWU's that should fit... like the front end off a GSF750... its even got the same brakes... plus the forks are fully adjustable if I remember. The USD will not have such a small enough diameter to fit.

Not that fussed about USD really … sure they look nice and all, but I am just after something that works well and had decent brakes, I’d rank cost and effectiveness higher than cosmetic. For this I need sports bike forks!!

I’ve looked it up, the SV has 41mm forks.

I’ll have a look and see if there are any sports bikes with 41mm forks.

Oh … and there is no point going for the GSF if it has the same brakes as I have now!! Also I doubt the forks are much better?!!?!!? I want some off a sports bike.

[northwind]

You don't just need the tube size to be the same though, you also need the spacing to be the same or similiar, or you'll have problems with wheels, plastics, disc spacing... Also, you'd want forks to be from a similiar bike, so that they'll be in the right damping and spring ranges- if you need to change that, the price goes way up.

SRAD yokes aren't expensive though, mine were £50 for both, plus I think it was £40 for the bearing to fit it. That wouldn't pay for a custom axle, if you tried to fit a hybrid front into SV yokes, for example.

And the GSXR bits, being built for a sporty bike of much the same dimensions and weight, work well without modification for a street or trackday rider- unless you're a big 'un, where revalve and spring becomes helpful.

Another advantage of the SRAD (or Y-K3 forks), 750 in particular, is that those are pretty good forks.

Good points, well made!! :)

So how much am I looking at all in for a 750 setup?

[northwind]

Less than the price of an SV650 front end, if you're careful :)

Wheels are generally around £100, the silver ones seem quite common. It's the same wheel on all the SRAD 750s and 600s, TL1000S and R, and Hayabusas.

Discs... You can pay what you want there, starting from around £50 for scabby thin ones. I got the Braking Point ones from Ebay

because I was simply sick of bidding and failing to get standard ones :) But I don't entirely trust them, if they were to warp tomorrow I'd not be shocked. Remember you can use any GSXR from SRAD onwards, right up until hte introduction of radial brakes, and also TL1000S or R, and any Hayabusa. I think GSX13 and 1400 too.

(that's, and don't quote me here, K1 and K2 GSXR thou, 96-2003 GSXR 750, 97-2004 GSXR 600, any TL or Busa. I could be off by a year or so, but they all look basically the same)

Forks, yokes and brakes can vary a lot. Mine were £50 the yokes, and around £150 for the forks and calipers. Be careful here, very easy to get duff ones. RWU 600s will be cheaper, usually. If you go 600, get later ones, they're better- but I can't remember which years, Rob#70 knows though.

Think that's about it ;)

[Robw#70]

I paid
£310 for 750K5 forks, yokes, spindle and calipers
£100 for TL1000 Dymag front wheel :lol:
£50 for a Hayabusa front wheel
£100 for 2 sets of 300mm discs OE

It pays to be patient with ebay and keep to your maximums, but then again got nearly £900 for the std stuff off the bike 8) so I blew the difference on woodcraft clip-ons, brembo master etc

[northwind]

I stole all my parts

Next time I need a bit, I'm sending you shopping :shock: Even on the only bit I beat you, I was buying older parts. No fair.

[Robw#70]

yes but then I blew over £750 on a set of flatslides :shock:
