Kawasaki ZX10R titanium wheel axles and 7075 alloy swinging arm spindle

Posted by on Jun 27, 2015 in Uncategorized | 0 comments

Here’s a set of spindles for a Kawasaki ZX10R, the wheel axles are titanium and the swinging arm spindle is 7075 alloy, coated with Surtek 650 for corrosion protection. I modified the rear spindle slightly, the shaft is 20mm but it has 18mm dia thread as standard, this meant that either i had to bore a 10mm hole all the way through or bore it 14mm all from the head end ending just short of the bottom of the threads. This wasn’t an option as the drill would have wandered badly over that length. So i bored it 14mm from both ends to meet in the middle then cut a 20mm thread instead of 18 and made a new 7075 alloy nut to suit. The is no compromise on strength and makes for a lighter and better axle....

These are front wheel and swinging arm 7075 alloy axles for a Suzuki GSXR1000K7 I’ve just made for a customer in Greece. His oem axles weigh 700g front and 683g swinging arm, his aim was to get the combined weight down below 800g, we succeeded!

The Guzzi Project *2

Posted by on Jun 21, 2015 in Petes Project | 0 comments

I’m now half way through stripping it, but because just about every nut and bolt is seized in its taking some doing and a lot of grinding discs! I’m not going to tune the engine particularly, i’ll lighten and balance what i can, skinny some bits down where possible, but what i’m interested in at the moment is getting it as light as i can, then the few horsepowers it has can be used more effectively. I’ve ordered an alloy tank, seat, mudguards and side panels for it from John Williams and spoken to Racefit about a titanium exhaust system, which will cost more than the bike is worth! But if i seriously want it as light as possible its the only way to go. Everything i’ve managed to get off it so far is in a poorly state, all three callipers for instance have had the bleed nipples snapped off and a screw inserted to stop them leaking, and on one of them one thread to hold the 2 halves together looks like its been drilled out and retapped off centre. Everything is like that, it was running a year ago, but by gum i wouldn’t have wanted to be on it! only one set of brake pads had any friction material left on, the other 2 were down to the...

The Guzzi Project *1. As I bought it

Posted by on Jun 21, 2015 in Petes Project | 0 comments

Its yonks since i had a project, the last bike i renovated was a Guzzi T3 about 14 years ago. It had been my road bike for a few years and needed an overhaul. For the last 5 and a half years i’ve been making stuff full time for everybody else, so i thought its about time i did some for me! I sold my last bikes 3 years ago and this is the first time since i was 17 that i don’t own a bike, its a weird feeling i can tell you! So I’ve bought a Moto Guzzi V50II from my friend, its a shed. My idea is to lighten it as much as i possibly can using only metal, as metal is what i do. So no carbon or anything easy, just lots of titanium and alloy. I’m tempted to have a lightweight frame made for it, but i want to keep the big chunks as standard, so oem frame and wheels, but everything else is fair game! This is how it looked when i bought it, it actually looked a lot better stood in my yard than it did when i started to strip it down. It had been stood under a cover outside for over a year so I had happy hours with a grinder to get half the nuts and bolts off!    ...

Yamaha R1 7075 alloy rear wheel axle

Posted by on Jun 20, 2015 in Uncategorized | 0 comments

As we all know 7075 alloy is not recommended for rear wheel spindles. The added forces from the drive can be too much for them. But this is for a track bike, it will never see the open road, on top of that it will be removed after every meeting for tyre change so can be inspected and checked before every outing. Even so i can give no guarantees as to how long it will last or the manner in which it will fail should it do so. Its very nice though…..
