XS650: Winter Tyres   Leave a comment

I don’t fit my neighbour’s norm. They’re all old. Mostly their kids never visit them. I have long hair. Work from home. Look after the kids (preschool) while my wife goes to work. Listen to ‘loud’ music (means: non volks-musik, non schlagermusik). And ride motorcycles. As do most of my friends. They really don’t understand that I choose to ride the whole year. Also in winter!

Mostly the weather is user-friendly. A few days of snow. Melts in a day or two. What really gets up my nose, literally, is the fucking salt. You don’t see it (until the bike begins to rust). But, you sure can taste it. Give me fish’n’chips any day. No vinegar.

The last couple of winters were snowy. Last year was particularly cold. And I got caught a couple of times. 100-200mm fresh snow. Just as I was about to head home. A 20 minute trip took 3 hours. Mostly I laid the rear wheel in the gutter for traction. Driveways were a killer. Off-camber corners deadly. Rising and dropping slopes a challenge. Both feet skimming the ground. Tyres crunching virgin snow. Pedestrians and cagers both, jaw-dropping unbelievers. The worst were the last 200m. Our street. Never cleaned by the city. Underlaid by ice.  !!FUN!!

2010 the German Govt made winter tyres compulsory. Or did they? “ bei winterlichen Straßenverhältnissen geeignete Reifen zu verwenden sind ” by winter road conditions appropriate tyres are to be used.

Problem is, these are hard to find. Many bikes are simply not catered for.

For the XS650 I found Heidenau K60 Snowtex. 4.00/18 64S for the rear. 100/90-19 57H for the front.

The SR500 was more of a problem. Heidenau K60 Snowtex 4.00/18 64S for the rear (same as the XS). Heidenau K37 3.50/18 62P for the front (drum brake). Profiles don’t match but are a TÜV accepted match.

Not even bothering for the SRX600.

I found these tyres on offer in the internet. Reifen.com was offering the K60 for €71 and the K37 for €68. I went to my local branch to see if they would order them. Wanted €134 for the K60 and about the same for the K37. Just for the K60 – over €200 mounted! Cash up front. And they wanted to data-mine my name and address – said it was for warrantee purposes. What a croc-of-shit! All I need for that is the receipt. Needless to say I walked. Got back on the internet – €127 delivered. Total price. For both. From someone else.

So – Reifen.comgo fuck yourselves!!!!!!!!!!!!!!!!!!

Am interested to see how these perform. Good that I had an extra set of wheels for both.

K60 Heidenau silica

K37 Heidenau silica

When you get them make sure they have the MS sign on them. Summer and winter profiles are identical.

It’s been a while since I rode with enduro style tyres. The difference was startling at first. Especially the front. Until the block edges began to wear the wheel wanted to track straight. I literally had to slown down, steer and consciuously use my body to negotiate corners. A bit like sidecar riding. This didn’t last. But I wasn’t prepared for it.

And I’m still waiting for the snow!

XS650: Ice and Snow   Leave a comment

Back in the day I was a geologist. Used to take winter contracts in the Yukon and NWT. I’m a night-owl. Just as well. The days are short. Winter contracts also solve logistical problems: lack of roads and abundance of water. Snow and Ice. Snowmobiles can go anywhere and there are no bloody bugs. You have to be somewhat ‘special’. Cabin Fever is a real problem. Violence and murder are real risks. For women-so is pregnancy.

One of my fascinations was the Trans Canada Snowmobile Trail. Had a lot of fun exploring this.

 

trans-canada snowmobile trail

 

everyone needs a distraction

 

My distraction was Ice-racing. Had an old Jawa. Similar to a speedway bike. Longer wheelbase. More rigid frame. 2-speed box. And spikes! Around 90 in the front. 200-250 in the rear. Up to 30mm long.

 

ouch!!!!!

 

screw heads

 

more screws

 

sensing a theme here?

 

for more normal snow/ice riding these claws are handy

 

Longer guards are mounted. Affords a modicum of protection.

Riding style differs from flattrack. The spikes (or studs) bite. No drifting around corners. Need to lay the bike down. Handlebar almost scraping the surface.

 

feel like you’re going to crap out

 

a leaning sidecar outfit with leaning wheel … takes some getting used to … hard to keep the lean in a corner … need to coordinate effort righting as you exit the corner

 

more conventional sidecar setup

 

Believe me. That air is cold. Wind chill factor XXX. You don’t feel it til later. As you start to warm up again.

Was chatting with Jukka from the XS650 Group in Finland. Asked if anyone was ice-racing an XS650. Thought maybe there was a vintage class running.

From Jukka…

the beast!

 

# 47 … ready! set! ….

XS650: Primary Gear Lash Tolerances   Leave a comment

This too has been posted. Again interesting enough to warrant its’ own post. Something that, in all the years I’ve been playing with motors, I’ve never really considered.

XS650: Gearbox/Gear Spacing   Leave a comment

This was interesting. So I’ve given it it’s own post. Yeah, I know. It’s in the previous post too. However, if you’re doing a search, you will most likely miss it.

 

259/1 … gearbox spacing

 

259/2 … transmission axles and gear spacing

 

259/3 … spacing, gearbox

 

259/4 … spacing, transmission axles and gears
