duckboy Posted May 20, 2011 Share Posted May 20, 2011 i know my R12RT manual states a max speed w/ sidecases mounted to be ~80 mph (can't remember exact #), but, i wanted to take a survey of what speed some of my fellow R12RT owners have run their R12RT's up to w/o any structural deformation/damage to their sidecases. i personally have gone up to 90mph for short periods w/o any problems. thanks for your help. duckboy Link to comment
RTs4me Posted May 20, 2011 Share Posted May 20, 2011 80 mph, eh? You have two sidecases, so I reckon it's good for 160 mph!!! I've seen a sustained 100+ mph on the German autobahn, two-up, fully laden, tank bag, sidecases and large topbox. But don't take this as a recommendation Link to comment
RT66Rider Posted May 20, 2011 Share Posted May 20, 2011 120+ for maybe 3 miles, 2 up with both side cases & top case. Link to comment
dirtrider Posted May 20, 2011 Share Posted May 20, 2011 Afternoon duckboy Well that depends on if it is GPS measured or speedometer measured. Short bursts to 130+ with side cases & top case and 90-100 sustained for a substantial time frame. I can’t tell much difference with the side cases on of off but I can definitely tell the top case is on in high side winds at speed. Link to comment
GRB60 Posted May 20, 2011 Share Posted May 20, 2011 Oops! Guess I should have read that manual before riding it home from the dealer... Link to comment
duckboy Posted May 20, 2011 Author Share Posted May 20, 2011 hahaha, thanks, everyone!! don't know why the manual states such a low speed w/ the sidecases. can't see how those germans on the autobahn could keep it under 80!! thanks, again!! best forum ever!! duckboy Link to comment
BerndM Posted May 21, 2011 Share Posted May 21, 2011 hahaha, thanks, everyone!! don't know why the manual states such a low speed w/ the sidecases. can't see how those germans on the autobahn could keep it under 80!! thanks, again!! best forum ever!! duckboy Its called C-Y-A (Cover Your Ass) because BMW doesn't want ANY responsibility for any damage to you, your bike, or any other vehicle or person that MAY get smacked by flying luggage. They probably feel pretty sure the cases will remain ON the bike at 80. Having put that warning in the manual, anything that occurs above their arbitrarily imposed speed limit becomes YOUR problem, not theirs. Kind of goes hand in hand with the very low weight capacities of the cases too. Same issue. Those Krafty Krauts!! Link to comment
CoarsegoldKid Posted May 21, 2011 Share Posted May 21, 2011 133 mph according to Garmin. I won't say where and I won't say next to whom. But we only traveled about a couple of miles before shutting down. Sustained over 100mph for miles and miles and miles. No damage to the bike or sidecases. Link to comment
tallman Posted May 21, 2011 Share Posted May 21, 2011 233.35 Km/hr w/extra large touring cases, top case. Everything was there when we stopped. Not an RT but same system cases. Link to comment
Penforhire Posted May 21, 2011 Share Posted May 21, 2011 Speedo indicated 122-ish, with a big rear topcase too. Was more stable than my heartbeat. Link to comment
Den Hieperboree Posted May 21, 2011 Share Posted May 21, 2011 My 2008 R1200RT Rider Manual states 180 km/h in combination with the side cases and/or top case. Did 170 km/h today with side cases and passenger, no problem at all. Den Hieperboree Link to comment
1analguy Posted May 21, 2011 Share Posted May 21, 2011 Keep going faster until one of them falls off. Then let the rest of us know how fast you were going, so we can avoid the problem... Link to comment
ScottT Posted May 22, 2011 Share Posted May 22, 2011 GPS indicated 145mph... redline in 6th. Rock stable. Had it up to 140 with trunk. NOT recommended. Link to comment
TF1200RT Posted May 22, 2011 Share Posted May 22, 2011 Garmin said 134 without top case. Rock solid. Link to comment
SuperG Posted May 22, 2011 Share Posted May 22, 2011 2 side cases, one Givi top case and a large duffel bag on the pass seat hanging over the side cases along with tent poles and hiking poles sticking out. We were heading home from a week long camping at Bigbend Nat. park in Texas. A long flat straight road ahead of us, we could see at least 2 miles ahead, no traffic. Throttle cranked WOT, windscreen all the way down, me laying flat on the tankbag. Got up to 135 indicated and it flat lined. The bike felt stable just as at any other speed. My mind and body was not, kept thinking about the consequences of "what if". We slowed down to close to speed limit. I hope the side cases stayed on because of the great German engineering and not because the duffel bag was holding it down:) Link to comment
