Got an incipient tank-slapper as I pulled through redline in 1st gear, doing say 75 mph. Lifted the front wheel just off the pavement, the tire caught some irregularities, and wham-wham-wham, it started to slap. As soon as I got the front tire back on the ground all was well. But that bike has 23.5 degrees of rake, very steep.(04-28-2014, 09:34 AM)Dave_imp Wrote:(04-26-2014, 04:09 AM)tattak_imp Wrote: Hi there,
i am willing to fit my CB1100 2013 with some kind of steering damper,
so far the only option seems to be a pretty expensive ohlins rotary one,
i have searched the forum and the web but can not find anything else.
Tips? Ideas?
Thanks
Hi Tattak. It appears that some of the responses to your question so far have been a question as to why you want a steering damper. Are you experiencing a tiny amount of head shake at approximately 45 mph? My 2014 Deluxe has shaken the bars at approximately 45 mph while decelerating. I can just barely feel it through the bars, and I took my hands off the handlebars once and could see the bars shaking a tiny bit; and this is with a bike that has less than 600 miles on it, so I wonder what will happen as the miles build up and the tires wear.
Thanks.

Sounds like wheel balance is out on the front.
A tank slapper happens under harsh acceleration not the opposite.
I once followed a pal on his 20mile old CBR600 (2000) and watched him gas it on a bumpy road, only to leave black sidewinder like rubber streaks on the road. He let go of the bars to avoid a crash.
The CB1100 is not going to have that issue. The Ferret is right, that deceleration headshake is common and not really a safety concern.
