GSXR front end finished

[650]

Forgotten if I asked you by the way (and I appreciate piston size differences) what size is the MC on yours?

no 650 wheel doesn't fit, its only the 'diamond spoke' gsxr that fit which is same as sv thou.

i use bandit 1250s MC as its naked 'square' type, works just fine with radials. i had a gsxr radial MC on at one point and tbh there is not much difference. i like 'feel' to my brakes so the more i squeeze the more it brakes rather than all out 'bite'. i hate bikes that have brakes that feel like an on off switch, but on the other side i also hate bikes that have brakes that you end up screaming stooooooppppppp.

That's all dictated by the ratio of MC to caliper piston surface area. I think your piston sizes are 30/32 on the caliper, I'm guessing the master cylinder size is 16mm?

dont have the foggiest what size the MC or pistons are. all i know is i like the feel of the setup. might be a bit useless for racing but on the road its lovely.

a lot of people seem to think that race setup is best when nothing could be further from the truth for road use. race setups need a lot of heat to keep working at their best or they will glaze up and cause fade and turn the brakes wooden.

Did my research and it's 14mm, same as the standard GSXR MC

Bit of an update on this, I ended up buying the Bandit MC and it's done the trick. I know the calipers are still capable of more but I can't justify a brand new RCS19 right now.

Otherwise, I had some issues with low speed weave. After a lot of research, the consensus is that tapered bearings require zero preload, almost erring on the edge of loose rather than any form of tight. I've backed off the steering nut a lot and it's helped - just need to fine tune it.

I had a dent in one of the exhausts from a close call side swipe on a roundabout, I've swapped over the cans but didn't like the plain silver finish, so I've wrapped both in carbon effect vinyl (which is fine, the heat's not an issue) and put some cheeky Fiat Abarth scorpion stickers on there. I also removed the belly pan stickers as I ended up not liking the look.

Next up, the forks will go off to Maxton for a complete revalve and I'll buy a Maxton shock with matching spring rate etc. Beyond that, I think I'm content with it now. Although I might get an Mt03 headlight and a smaller gauge, but I'd like to retain the dealer error code function, so I might hire a regarded bike sparky to do the install and make it so I can switch back to the stock ones easily - won't cost much. Here's how she's standing

Did you say you were going to write a fork swap guide?

At some point, things have been a bit bonkers recently and I'd like to do it with a lot of photos etc. So I'll probably make a start on it at some point in August

...it's AUGUST, mutherfukah...!!!...

haha! You're not wrong, this month is gonna be hectic but I'll see what I can do. In all honesty, it's just the following:

1. Remove existing front end
2. Tap out existing races
3. Tap in new races
4. Remove existing bearings (if there) from the GSXR stem
5. Tap down new bearings onto stem
6. Put stem into headstock
7. Put top bearing in place
8. Tighten steering nut to required torque (if tapered, zero preload - as in finger tight) if roller bearings - 40Nm then back off quarter to half a turn
9. Tighten steering stem lock nut (80Nm)
10. Put top yoke in place
11. Tighten top yoke lock but (90Nm)
12. Slide forks in, put wheel on. Etc

There's obviously a bit more to it - like adding handlebars etc, but as there's so many factors there (bar height, type, throttle and brake cable lengths etc) there's not much sense in me covering every possible scenario - a bit of logic from the user is required, and/or some direct questions on forums.
