I am hoping someone here knows what the stock fork spring rate is on the Bandit 1250? Race Tech usually has that info on its site, but not for the 1250 version.
Thanks,
Mark

I'd be surprised if it's much different.'20 Ducati Multistrada 1260S, '93 Ducati 750SS, '01 SV650S, '07 DL650, '01 DR-Z400S, '80 GS1000S, '85 RZ350 -
Isn't that dependent on your fully geared weight (plus that of any passenger) plus your style of riding?
Maybe find a similar use bike of similar weight on their charts?1982 GS1100E V&H "SS" exhaust, APE pods, 1150 oil cooler, 140 speedo, 99.3 rear wheel HP, black engine, '83 red

Seriously, that would work if there was any rhyme, reason or logic to how manufacturers selected rates. But there's not.
Crazy example: Kawasaki. 3 bikes. Ninja 500, Ninja 650, Kawasaki Concours (the original one)
Fork spring rate on the 500, about 0.50, way too soft even if you weigh 90lbs. (Actually, too soft even if you weigh nothing)
Spring rate on the bike that replaced it, the Ninja 650, basically the same weight and target market, a progressive spring that started at 1.1 and went to 1.6!!! Stiffer than I would put in Gold Wing.
The Concours, which weighed close to 700lbs, got 0.72s.
The other OEMs aren't much better.'20 Ducati Multistrada 1260S, '93 Ducati 750SS, '01 SV650S, '07 DL650, '01 DR-Z400S, '80 GS1000S, '85 RZ350Comment

In case you feel like more giggling, a few years ago (I was 20 pounds lighter) I installed .90 Race Tech straight rate springs. I'm not a hard rider around curves, but I quickly got the feeling I should have gone to 1.0.
Good luck, I don't know any more jokes.1982 GS1100E V&H "SS" exhaust, APE pods, 1150 oil cooler, 140 speedo, 99.3 rear wheel HP, black engine, '83 red

That is how to determine what the rate should be, but that does not tell me what Suzuki used in the first place...Originally posted by Rob S. View Post
The reason I ask is that I want to make my own decision on the rate for new springs. Race Tech recommends 0.96kg/mm springs for touring street riding, but I would like to know how big of a jump that is from stock. The bike is very soft and plush right now and I don't want to lose that character with the new springs, just firm things up a bit for when I am loaded and two up on weekend trips.
There also seems to be a lack of decent shock options. Dale Walker sells a shock for $690USD, but it does not have adjustable compression damping and only two choices of spring rate (with no info on what those rates actually are). Traxxion Dynamics sells a version of the Penske twin clicker without an external reservoir for $900USD and $1100USD with a reservoir. The Ohlins twin clicker with a reservoir is also $1100USD. I would like something like an Elka twin clicker but they don't seem to sell street shocks any longer.

Go with 0.95s. It will be more comfortable with those, not less.'20 Ducati Multistrada 1260S, '93 Ducati 750SS, '01 SV650S, '07 DL650, '01 DR-Z400S, '80 GS1000S, '85 RZ350Comment
