Hi, I am new to this site and to owning a fireblade. I bought my rrv last summer, and I love it, however I had a new under tray fitted and the fitter said that it would benefit from a Jack up kit.
So I went for it, 50mm , but now it feels really weird. I dont feel confident on it, and it feels like it wants to jack knife lol. l have only ridden it 3 times since the kit has been fitted, so is this something I Will get used to with practice, or is it a bit dangerous ? l could just go back to the original plates, but it does look good.
If anyone has done this , and could offer some advice, I would be grateful.

Were they just the triangles on the rear linkage? If so I've been eyeing some on eBay and thought the 30mm was too much. How do they determine the height change? From the ground to the underneath of the rear fairing? From the rear axle bolt to the top of the seat? A static point on the linkage itself. 50mm is huge, it's gonna put a ton more pressure on the wrists and front end, making the rear feel like it's not connected to anything. I would scrap them and go a bit smaller. 25mm I would recon would be good. But it sounds like the guy who was pushing them on you was only going for added looks, and not functional practicality.

50mm is a huge change in your bikes geometry. huge. it would really need to be completely gone thru in terms of setting the suspension up. everything would need to be set accordingly but even so i think 50mm is going to be too much. a lot too much. ive never owned a 97 900 so i dont want to put my foot in my mouth because im no expert on suspension or those parts on that bike but i had an old 96 zx7r that had a 7mm jack up on the rear n it was noticeable and required some major suspension tweeking to dial back in after the change. i can only imagine what a 50mm change would do. i cant imagine that is intended to work with a stock front end?

the 7mm made the turn in a lot faster on my zx7r. the less rake your front end has will increase turn in speed at the cost of straight line and higher speed stability.
