HP2 Drive shaft

a little dickie bird, told me that there was a problem with the standard drive shaft when used in the desert, BMW Ireland contacted BMW motosport in Germany and they granted me a modified shaft for my desert adventure, in the forthcoming Libya Desert challange

Less CCA with Odyssey

OEM BMW VS Odyssey 545
Battery Type: YTZ12S vs 545
Voltage: 12
OEM Capacity (Amp. Hrs.): 11 Vs Odyssey 14
Dimensions: 6" x 3 7/16" x 4 3/8" VS Odyssey 5.17x 3.37x 5.7
Metric Dimensions: 150mm x 87mm x 110mm vs Odyssey 131x 85.6 x list says 5.7 I believe site error
Metric Weight: 3.7 vs ??
C.C.A.: 210 versus vs Odyssey 185

What you gain in Amp hours you trade for CCA which is more important?
and why

What you gain in Amp hours you trade for CCA which is more important?
and why

"The most important consideration is sizing the battery's CCA rating to meet or exceed, depending on the climate, is the car's OEM cranking requirements. CCA's are defined as the discharge loads measured in amps that a fully charged battery at 0 degrees F (-17.8 degrees C) can deliver for 30 seconds while maintaining the voltage above 7.2 volts."

Assuming the charging system is up to snuff isn't for our purpose CCA more important? based on the following definitions ?

the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.) .



--------------------------------------------------------------------------------
COLD CRANKING AMPERAGE:
(CCA) is the maximum amperes that can be continuously removed from a battery for 30 seconds at 0°F before its voltage drops to unusable levels. A 550 CCA battery can supply 550 amperes for 30 seconds at 0°F. This rating is only useful in the selection of engine starting batteries.

I think in this case CCA is a more realistic measurement - an indication of how long it will spin the motor before the dreaded 'click click' However being quite honest I had never heard of CCA before this evening

Irrespective of capacity and CCA, I think the odyssey batteries are better than standard lead/acid (like the OEM Yuasa) because they are more resiliant. They don't mine being drained completely and they don't mind if you don't keep them on an Optimate for months at a time.

Regardless of CCA I am inclined to agree and would also have the Odyssey over the Yuasa any day as it is a superior unit.

Kung Long WP22-12NE

RickA just checked out the size of the long battery, before you order you might like out the dimensions

I make them
Long = 181mm No Problem
Wide - 76mm No Problem
High - 167mm I think much to high to fit

Have now started the HP2 with the Odyssey 545 and it seems to have more go than the standard Yuasa

RickA, thanks for the advice,
Cant understand why Wunderlich is offering this battery as a replacement for the HP2?
Will contact my dealer to order the 545 instead.

Philgunn,
Great pics mate, this helps me a lot.

HP2 Battery

Phil,
You were right, the new Kung Long battery I have just recieved is too tall and will not fit!

I will check that it will fit the 1200 GS/GSA and offer it up on the forum for sale soon.

Will order an Odyssey 545 asap & get that in. This parping around has gone on far too long! Need to get out on the bike!

Cheers, Rick.

p.s. Phil - fitted a Scotts ( Ohlins) damper to the steering - think it will make a big difference to the handling, esp. on high-speed rocky going. Will let you know.

I think you have just got a new name
"The Battery King"
and talking about toys , got my Wilbers Shock and springs today
will post a pic later

As an insurance against getting stuck on a trail somewhere with a flat battery I now have a PC545 ready to install.

Phil, how did you sort out the strapping arrangement? From what I can see the standard battery clamp (and associated gubbins) wont fit with the PC545.
I was wondering whether the 1200GS strap could be used. Or is it a DIY job?

Cheers

 

[Spout]

Eventually I've got round to buying the 18mm spanner and jumbo torx socket to take off the shock, I also bought a 1200Gs battery strap (£8 ), and so have set about changing the battery.

The PC545 only just fits in - can't remember exactly how I did it, but if I'd not seen Phils photos I might've given up A bit like changing a battery on a G/S

The 1200GS strap fits quite well - obviously lines up with the bolt hole - but I had to put a bit of packing on the top of the battery. The frame rails will stop the battery sliding about anyway

Only annoying thing is that I couldn't use the brackets that hold the electric gubbins. I'll never use the socket anyway, and a bit of duck tape has tidied things up until I can fabricate a hanger.

I've just got back from a couple of miles trailling - shake down tests - all OK

Hello
The Odyssey PC535,the one that Odyssey recomments for the HP2 DOES THE JOB.It's a puzzle at first and quite some work but it fits into place perfectly.They provide everything needed in the box.A metal strap,the screws meeded,instructions and all.You have to attach the HP2 small plastic base of the underseat electric socket on the new metal strap.Finally all the electrics are well secured in place.
The way to do it is to remove the rear shock AND the wheel.Then you bring the battery into place following the route through the rear shock's space upwards.
Yes,the HP2 is a true R80G/S descendant

Phil,

I just bought a HP2 and will ride in the desert. Could you please let me know what is the part number for this modified shaft? What is the difference between both, and what happens if I use the standard one instead?

Thanks.

Hi Mago - BMW HP2 Driveshaft

I was told that the Standard BMW HP2 driveshafts have a problem in the desert due to constant power Application, BMW had a batch of stronger one's made by HPN in Germany
the shaft has a longer overlap and more of the Rubber damper , the overlap is about 30% bigger than standard , There should be a picture here in the archive of the shaft
I dont Know what would happen if you use the standard shaft in the desert,
how good a rider are you , if you are a expert maybe you should contact HPN and get a price for one

regards

Phil Gunn

Thanks Phil, checked HPN site.
I am not a professional rider but I do ride rallyes. and would describe my usage as demanding of the bike. So I think I might need this..

 

[(RIP) philgunn]

HPN site

did you find details on the HPN site ?

Do you mean this:

The site talks of 25% more strength to deal with torque load... but no price!
