must say 21 is the way to go if you go offroad - the HP saved me a few times that I knew if I was on the 1200 I would have been down - would be nice to fit the motard rims on the Hp to go and blast the lowfelt passes

Go to Europe, drive around see where a 21" is going to help them "NOWHERE" their twisty riding roads are better surfaced than our highways 8)

Only the normal adventure, the R will still keep the 21.

OK, so I T-Boned a car last week and in the quote, there is a cost of R14,000 to re-lace the wheel and sort out the rim, now I'm thinking...

1. Do I go for an interlaced(lubeless - more expensive) 21" conversion while I'm at it? (And what rim do I use? Heard something about the older R80 or R100?)
2. Do I go for a 'tubed' 21" conversion (how do I match the rims, can I have them 'purple anodised' for the R1150GSA)?
3. Do I go for an Excel tubed fron wheel and again...(how do I match the rims, can I have them 'purple anodised' for the R1150GSA)?

Some advice would be appreciated - VERY QUICKLY, I speak to the assessor later this week.

I would try to get a HP2 front rim.  (Tubeless)
Depending on the number of spokes for the 1150...

I've had the same wallet munching thoughts about changing the front on my bike to a 21''.
I've already got a spare hub.

I thought that the HP2 front wheels were 'tubed' and not 'tubeless'(interlaced) ?  I seem to remember that BMW had some issues with making them interlaced/"tubeless"...

AFAIK the HP2 is crossed laced tubeless. The spoke is on the collar of the rim just like the GS rim.
You can ask the HP2 owners about this.

But a much thinner rim ... that takes 90/90 not 110/80 ... better handling and tyre choice though IMHO.

Minimal, the rim would be 25mm more, but the tyre has less profile so maybe 10mm to 15mm difference  8)

Hi Welsh,
I've spoken with Mannie Koutsoudakis(ex-Auto Alpina & ex-Acme) now Dealer principal at Clearwater BMW Motorrad on the West Rand. He's going to 'make a plan' for me. (Next hurdle is to sort things out with the assessor...)

Missed this thread 'till now ....

I did the conversion on my GSA about two years ago. Used the R80GS 21" outer rim, bought new spokes and nipple ends from Northside BMW (speak to James) who also organised a used hub, rim was anodised by a mate who's in the business, lacing was organised by James and then fitted a TKC.  I made my own brackets for the raising the mudguard.  Whole lot set me back about R11 or R11.5k.  It is a tubeless conversion.

I've upgraded the GSA since but kept the 21" which I alternate with the 19 depending on the ride.  All the reports of improved ride are accurate!

My only negative is that the TC and ABS can't sync and switch off with an error code and become ineffective.  Not important for the dirt stuff, but I want it on tar.

Explain the TC and ABS problem?

I have no ABS issues. (2007 model, so no TC  :thumleft:)

I simply fitted an ABS ring on the 21" rim and change wheels as I want.

I have the wunderlich rim which is laced on a standard BMW front hub

The only REAL isuue is that, with the 21",  the front is raised and you need to adjust the headlight way down all the way.
I realised that after the trucks started flashing their brights at me one night.

Making some beam guidance mark for each rim's height on a garage wall will take care of that.  8) Adjust before you leave home.

That needs to be done in any case if you are loaded with luggage for a long trip

I have been cosidering upgrading my rear shock with a longer sping to 'level' the bike out more (plus I want a fulle adjustable rear shock in any case)
