Must give NP credit for sighting his source! And no knock against you NP, but I don't buy their results. They report the single disc Kaw stopped in a 115 feet!!! NO way, just didn't happen.
Yep , remember them well . In fact , had friends then AND now that own(ed) kettles . No way no how would a steamer stop that quickly from 60 MPH . Lots of testing done in that era was suspect. I guess you are telling us that a 1970's motorbike with single piston brakes and period tires would stop as rapidly as some of the best modern bikes , sorry dude . Dusty
Lots of testing done in that era was suspect.
No! Say it ain't so..
Aw Chuckie , collective memory tells us that all of those tests were completely accurate Dusty
The early G8 mapping was really very ordinary. The GRS8V-01 map had nothing at the bottom and then a huge surge at 5.5K, it felt like a 2-stroke coming on the pipe but not in a good way.The 68S map which was not homologated for road use was a huge improvement, in fact it remains, in my opinion, the pick of the factory maps. The GRS8V-03 map which is what is used on all of them post about 2011 is an improvement but it's a real compromise and remains pretty unexciting compared to what can be developed by someone with the requisite skills and Tunerpro.There is no longer any need to pay either silly money for half arsed solutions or put up with e poorly developed mediocrity of the factory maps.Pete
If I shower any more praise on the 1200 Sport on this forum, I'll get booted off! She still provides a relaxed, comfortable ride after 62,000 miles. A plush ride, by comparison with my recently-sold Griso. I don't find the 1200 Sport lacking in performance, but in a straight line drag, my seat of the pants dyno say the Griso would have eaten the Sport alive starting the run at any speed. I think I set the red flashing 'shift' light to come on at approx. 7200rpm on both bikes, and either bike was ready to keep on spinning up. I think you're correct on two counts ..... the Sport is a more relaxing ride (IMO) than my Griso was, and yes, the 8vSE did have that "urgent want to run" feel to it. That bike would roll from 70 to 100 quicker than my reflexes could keep up. Or for that matter, from 30 to 70! It was a little bulldog. I'd love to have that engine in roller version in a big Guzzi standard, or, for that matter, in the 8v Sport that was only made available overseas, but not in N America. 8v Stelvio is too big/tall for me, and I have no interest in the 8v Norge.EDIT: Either the Griso or 1200 Sport would be a hoot on AZ 89/89A from Prescott to Jerome. Unfortunately, both times I've been on this stretch of highway, I've been driving, not riding![/quoteI was thinking the Sport would be a pretty nice bike, at 62,000 miles I'm sure you've got it well sorted out. Did you have to flash the ECU or does it run ok without it? Do you think the 2v is as torquey as the Griso in the lower revs? I wouldn't think it could match the Griso after 5k, they pull pretty stout.AZ 89/89A is a great road I got a chance to enjoy it on my 96 GS1100 which was a decent handling bike. I need to make it back up soon.
You're tempting me to exert some forum power and delete the original post ..... but I won't. This is too interesting. Re the GS and it's 60-0 stopping capabilities, draw your own conclusions.- drum rear brake, cable operated.- single front disc with (I think) two piston caliper, maybe only one.- very soft front springs that allow a lot of dive.She isn't a quick stopper by any stretch of the imagination. Best thing going for stopping the GS is the fact that the bike is sub-500 pounds.Let the water buffalo contest continue!BobPS - Happy holidays to all you WG members!
As seems to be the usual case, you can't even imagine half the things others know.http://www.abacuscaralarms.co.uk/bikes/Test_Reports/Suzuki_GT750_H2_test.htmlThe collective memories of a lot of people who also read the published tests of the 60-0 stopping distance of 117' by the GT750 is there for the culling.The report above show the distance to be 118' but bested by other tests. I can still remember those years, you?For some reason, some can't believe a 70s era bike couldn't stop that quickly.
Interesting , the test quotes 31 ft 8 inches to stop from 30 MPH . Now , if you understand braking physics , that translates to 126 feet 8 inches from a true sixty MPH . So ... Dusty
Just like a lot of dyno's have horses with short legs, they had a measuring tape with long feet.
Don't have to , physics is physics . In fact , looking at a comparison test of several modern bikes , the best stopping distance is a Street Triple R , 124 ft . Now , quite a few factors are involved here . Center of gravity , wheelbase , front/rear weight bias . A long bike with a low center of gravity with modern brakes and tires will be easier to stop than a short wheelbase sport bike . AND certainly the forks ability to not compress completely under hard braking is a large help . What I am saying is , as are several other here , the testing methods employed in 1974 were suspect . Hell , oftentimes they just quoted what the manufacturer told them . Dusty
One of my RE5s....If you use just the front brakes it will go from 60 to 0 in about 10 minutes. If you use just the rear drum about 8 feet.
