RGV250K caliper pistons being developed over the winter

Hi,
TITANIUM Front caliper pistons for the NSR250 are now on sale and look amazing in the caliper.   
They have 2mm castellations to allow air to flow inside the piston and help cooling but they also reduce the contact patch with the brake pad and thereby reduce the heat transferred to the caliper piston, which in turn reduces the heat transferred to the brake fluid.
Titanium if you don't know is a poor conductor of heat so will reduce further still heat transference to the brake fluid.

Also on sale are NSR250 (MC28) Titanium front wheel spindles which save 100gm of weight.
They come with a hard Titanium Nitride coating and are the same dimensions as the original part.  

RGV250K (1989) rear caliper piston
Coming at some point in the near future is a Titanium rear caliper piston for the RGV250 but also caliper pistons for the later RGV250T (VJ23) model

I'm not sure if its worth having caliper pistons Nitride coated.  Yes they look amazing in the bright gold colour but whether it aids performance over a non Nitrided piston I'm not sure.   
The belief is that the TiN hardened surface coating will allow the caliper to move more freely.


These are new in.  If you have a YZF-R1 or R6 you'll recognise this banjo type.
THey're M10 x 1.25mm thread type

As people put their bikes away for the winter there are a couple of months where I can get new products made without the craziness at the start of the year where everyone is preparing their bikes for riding.  
So, if you have ideas for new Titanium products to be made now is a good time to get in touch.
The head studs for the Pre 1988 KX500 is the perfect example of this.  The OEM head studs aren't being produced any more and a customer sent me one of his.  I got a small run of the made and they're selling well.  He was very happy with his studs!   :)

That's it for now.  Hope you've enjoyed the blog post and have a look at the titanclassics.com website to see if there's anything you fancy

Dudes!

Hope you've had a great summer.  New stuff that has been developed and some of which is now on sale are as follows. 
Here's a Honda fitting titanium pin that fits many calipers.  Part:45131-HA5-672 

The standard OEM part may corrode if the rubber sleeve perishes allowing water to get in, so this not only reduces unsprung weigh but will keep you caliper maintenance free for longer.

There are 10 Titanium front wheel spindles being titanium nitrided right now for the NSR250  MC28 and the first one will go on my bike of course, with a weight reduction of about 120gm I believe.
Here is also a picture of some castellated Titanium caliper pistons that will be on sale soon too.
The castellation is to allow air to get into the cavity of the piston as well as reduce the contact area with the pad which gets extremely hot.
As Titanium is a poor conduction of heat these pistons will keep the brake fluid cool under race conditions.

KX500 pre 1988 head studs

These studs are M10 to M8 thread and fit models before 1988 when Kawasaki went over to M8 to M8 bolts

That's it for now.  Check out the titanclassics.com website and let me know if there are any parts you think would be good to have in titanium

Cheers
