Getting right down to business......... Lets keep the issue clear: No Pre Load is adjustable with the K-tecks. Yes they are, 12 mm socket.
The wonderful folks at K-tek, found a market niche for SV's and Ninjas. We all love buying these new and second hand. But remember, our suspensions are 1970's design. Actually the 40's.
So.......... Could you drop the ktecks in? Yes. No, some machining is required.
Could you figure out your spring rate within 5 kg/mm? Probably. 5 KG???? How about 0.05. And they have rates from .70 through 1.20 in .05 Kg/mm increments. That makes for 11 rates in 0.05 kg/mm increments and over 22 if you split rate (use a .95/1.0 to get a .975) in 0.025 Kg/mm increments.
If you think you can work with the 5 different spring rates offered by K-teck: Go For It! I strongly suggest you figure out what Sag your looking to achieve, prior to purchase as the spring rates in this setup will determine your sag. Their is no pre-load adjustment. This is NEVER the way to select a spring rate.
Also, Food For thought: Our tubes are narrow as compared to any USD fork, Really? EX 650 and SV's have 41 mm stantion tubes. Same as: R6 06+, GSXR 600 06+, GSXR 750 06+, ZX 6R 03+, CBR 600RR 05+, Triumph 675 06+, and dozens of others from 1991 through 2015. The inverted fork front ends get their rigidity from two areas. First is the increased clamping area of the triple clamps. Conventional forks have the same diameter top and bottom and is the same as the fork stantion diameter (41/41) inverted clamp diameters are more like 50-52 top and 52-56 bottom. Also the tube wall thickness has a tremendous impact as well. I can tell you (with out naming names) that in the heyday of the Supersport wars, certain factory teams had several wall thicknesses to choose from at the track.
and having a compression damper in one side and a rebound damper in the other side may contribute to Fork Twist..... I'll be brief about this one, pure unadulterated bullshit. Well unless you are using a wooden stick for an axle, then yes, it will.
Since I have not personally tested, installed, raced or even experienced this product, many of us would be interested in your success and write up. Pictures Please! Woot Woot This is typical of the internet experts. No experience with a product or service, no expertise in the field, and not even a test ride, but "here is everything wrong with xxxx." And this is where I get my cynicism from.
