Shiny new tires

The big S was still equipped with the Metzeler Roadtec Z6 it came with when bought as a damaged repairable motorcycle. Ok, so I bought it in December 2009, almost 4 years from now. It had apparently stayed still in for a year before the purchase and, although these tires had plenty of thread left, given the mileage they certainly started their life on the BMW a year before the crash. Which makes a total of  4 + 1 + 1 = 6 years ... No wonder I'm power sliding at each roundabout exit. It's funny, but utterly useless and a bit ostentatious.

Old Metzeler has had its time

I was decided to finish them and change both front and rear whatever could be their level of wear before winter comes. But then came the rain and what were acceptable tires on hot and dry tarmac proved to be dramatically dangerous on soaked roads. They had become hard and slow to warm up. I loosed the front twice on the road back from work one day and with the bike straight the rear was sliding under acceleration. Time for a change.

I had read nothing else but good reviews about Dunlop Spormax, so ordered a set and had them fitted. It's been a new honey moon since for me and the R1100S. The tires' profile makes the bike feel lighter while offering high level of grip. With these new rubbers and the front Bitubo now up to its best, I can say without being disrespectful to the others that I never had a bike that much precise when approaching a corner and inspiring that much trust while leaned on its ears.

Unmovable

I know this is supposed to hold the front tire tight, but to this point it's getting ridiculous ... It took several minutes to get the bike out of its trap, leaving two one meter long trails on the ground.

It's the first time in 2 years this Matthys bike grad gets locked this way. It was last week, been used in and out for the whole week and haven't been able to reproduce again.

Kriega R25

If like me you use your bike as a daily commuter and need a laptop as your main working tool, then you probably have asked yourself what's the best way to carry it from point A to B already. And also doing so without causing any damage to the computer and of course to yourself, while still trying to enjoy the ride to work.

Along the years, I've been mainly using a Bagster kit (tank cover + tank bag), just buying a new tank cover when switching from one bike to another, but in the past 2 years or so I've been changing strategy. The reasons are fairly simple : 

- a tank cover alone still costs to much for what it really is.

- many times you have to give free it with the bike you've just sold. Too few people want them second hand or pay for this extra when buying your bike.

- some recent projects needed paint work and a tank cover has to match your bike's paint scheme.

So with no tank cover matching any of the current projects, I was left with the Bagster backpack which is actually bad as a bag that you carry on your shoulders (what a backpack really is ...).

With a brand new laptop now 2 full kg heavier than the one before and more miles to commute to the new job, I thought it was time for a change. After a bit of reading, I bought a Kriega R25 (pictured above) a couple of weeks ago. It's been really good since with its way of dispatching the weight away from your shoulders down to your back. There's a place where to fit the heavy laptop and still some more to put a pair of shoes plus some extra items. It's much bigger than the Bagster while still having good ergonomics that makes it barely noticeable when riding. I cannot recommend that product more.

A Vyrus and a Kriega ... interesting package

Renthal flat bar

Would Renthal flat bars fit a 955i Speed Triple ? No, the hand commands would hit the tank both sides.

I guess it had to be tried before being a hundred percent sure. These bars were sitting on one side of the garage and the SP3 on the other. At some point they had to meet one day. It would have certainly changed the riding position to something sportier and more suitable to my 6"2 frame.

Too bad as it's a nice item and would have been a nice addition while reverting the SP3 to an upright naked configuration. Let's put back the standard bars then.

Every little detail count

Big sporty german bike gets new turn signals to match already white rears. It would also need a good wash as well, but it gets ridden a lot and hard these days.

Forteen years set these parts appart and given the price it's no real surprise BMW are still making them. Every little euro count ...

The return of the Bitubo

The Bitubo front shock is back (was it gone ?), but there's something new about it ... Let me explain that a little.

The first time this shock was put on the front end, the main idea was to replace the 20 000-mile old Showa. Expectations were big : not only the Bitubo was supposed to work as a new part, but its higher specs - spring preload, compression, rebound and length adjustments - would mean nice improvements over the Showa's behaviour. But once fitted, the reality was sadly different. As soon as the brakes were grabbed, the R1100S wobbled like it could never regain balance again. The overall setting was too soft and not a single adjustment seemed to temper the ride. Though a complete setback admission, at that time the stock Showa was put back on the bike for the rest of the season.

And then 2 months ago, I resigned myself to do something about it and did contact suspension guru Eric Delcamp. His company Delcamp Energie is known to build among the most advanced shocks in France. They provide suspension units and services for rally cars and the Pro Twin challenge. We talked about the Bitubo and what could be done to improve things. Eric wasn't very keen on modifying what Bitubo had designed, but agreed to have a look at it and service it. He also asked a few questions about the Showa that he would agree to prepare. 

Fast forward a couple of weeks later, Eric called back to tell me he had put the Bitubo shock on the testing bench. The result was rather embarrassing ... for Bitubo that is. The shock wasn't working properly as if something was stuck in there that was preventing the shock to properly apply any sort of damping. Before calling that a complete failure, Eric decided it was now certainly worth to open the shock not only to repair it, but also to apply his magic to the internal components.

The shock was back home from Eric's facility before we moved house, so with very little time to fit it on the BMW, it's still unknown whether it's working properly or not. I'll figure it out later this month.

NGK spark plug reading guide

Enough with holidays ! Let's get back to work ! With now near 30 kilometers of twisty B roads between new home and work places, motorcycle is the weapon of choice. I've started with the BMW only to discover it was rattling again a bit when idling. Nothing to really worry about but there's certainly a throttle body synchronisation to put on the schedule soon. But I was also curious to know if the air/fuel ratio is still a bit lean, so I made a simple search and came across this guide on how to read plugs. Thanks NGK !

New home

It's been a while since I've last been posting. Working in our new house has taken much more time than expected. It took naturally priority over anything else, but given the result it was well worth the effort.

The new house means a new home for these two as well, even if they still have to share some space with unrelated garden tools ...

Work on the forks
