When i ordered the suspension i was a bit sceptical about compatibility as Nitron has listed only the duke 390/200/125 on their product info page. I tried messaging them about it on facebook and got this reply.
"I am afraid we haven't tested the compatibility between the two bikes so are unaware until we have the RC390 in our workshop.Sorry i couldn't be more help.Kind regardsAlex"
Dont know how hard it is for them to find an RC390 in UK to try and fix one. But anyway, i decided to buy one after enquiring at the KTM dealership about compatibility b/w the two. And also Ohlins list their KT301 and KT303 shocks as compatible for both RC and Duke. I was set on Nitron because the NTR R1 was the cheapest, most adjustable(for the price you get combined rebound and compression damping adjust, ride height adjustment and preload) and quality shock (internal floating piston design, alloy construction etc) i could find. Also it is a good 2kg lighter than the stock. Maybe more. Shipping was painfully slow and the responses to emails where equally slow. Paid around 400 pounds for the shock including tax and shipping. It reached me yesterday. Have to say that the quality is impressive. Now, i dont have any other shock other than the stock one to compare it with. But i am pretty sure that it will almost match the quality levels of some big brands. Installation was easy. Spring rate is 825lbs which is i guess really stiff. And i weigh around 150 pounds fully geared. They asked me about my weight, pillion weight and riding style to which i replied, and that is the spring they sent me! Initial impression is pretty good. a bit stiff for my taste right now but not as stiff as i imagined it would be. but i only rode around the block. Will do a proper ride once i fix the master cylinder too. Bought the master cylinder from webike japan. Fast shipping, reasonable shipping charges. Immediate response to emails too. It requires some modifications to the steering lock to avoid it touching the bodywork at full lock to the right. will try and fix it. If that fails, i will save it for my next bike.
