weight

Hello, I just purchased a '15 cup bike with 1mile on the odometer.(KTM had used it for a media event, this one had the least amount of rash) my intent is to use it for track days and club racing in the Sr group (I'm 60+). the front end seems stiff compared to the rear. the sag front/rear from...

Introducing our first designed and developed in house product! The simple and subtle rear tank mount! No its not much and won't make 15% gains like our air tube but it does make life easier. I was tired of having to pull the fuel tank to clean my air filter so I made a fix, this bracket is that...

Picked up my brand new, 0 mile, Cup on Thursday. Drove it down to Road Atlanta on Friday. Crashed it on SAturday. ;) ahahahaha Totally underestimated my weight and overestimated the suspension for my underestimated weight. I knew it was going to be an issue until I could get some springs but...

What are the options for full system exhaust for the 2017 RC 390 for maximum weight savings? There are many options for 2014-2016, but most of them don't work with 2017.

272.7 lbs with 2/3 of a tank of gas -at least that is what the math said after I subtracted the weight of the board the bike was sitting on. I’m not bragging and my goal was not go to great lengths to try to lighten the bike. This was merely a labor of love of tinkering and aesthetics. This is...

Hi all just a quick intro of myself. I'm probably older than most people who buy a RC... turning 50 this year and getting back in to riding amongst other goals like losing weight etc. From Australia, where these bikes are very popular. Bit of a fatso, but losing weight steadily. I'm also on the...

Well my original battery packed up and wouldn't retain any charge. So I splashed out about the same amount of pounds, shillings and pence on an Aliant Lithium fitment, Sportsbike Shop doing a sale. 1. I thought they sent me an empty box! 2. I thought they sent me a packet of cigarettes! 3. I...

I opened my bill for 2017 tabs and was shocked. My bill is 68.75!! Last year it was 34 bucks!~~ Why why! Read below if you want.. Sigh they raised taxes on everything by double. I would not complain if they did 5% per year, that would be logical, but double?! What if milk, gas or your...

I see that the general consensus is that the rear WP shock is an absolutely worthless piece of junk, oversized paper weight, good for nothing, throw away stock item. Please tell me why!

hey guys, wondering what things people have hacked off the bike to save weight :) Right now i am thinking: - Open airbox - small savings - battery - ABS removal + all the usual race parts, bodywork, rearsets, etc. What else can be removed? have people removed? -J

hello all, I've contacted the suspension guy at the track I'll be going to soon so get my cup bike all set up for my weight. He did some research and was unable to find information on what springs are currently on a stock CUP bike, and how to acquire new springs. He said I may be forced to buy...

Hi guys, as I've posted before, I have an insane and unhealthy obsession of grafting a twin disc setup into any bike I own. To that avail I want to swap out the wheels of my RC with those of either an Aprilia RS250 or an older generation Ducati. I believe either combination will be lighter than...

Hi guys, I'm planning on designing an exhaust system for the 390 series bikes. My goals are to : - 1) reduce weight. 2) make sure that the power/torque does not change for the worse. 3) Maintain the stock mounting positions. 4) reduce heat emission from the exhaust to the rear shock. I was...

I'm picking up my 2016 RC390 in a few weeks. I know that I will be upgrading the suspension. I've had premium suspensions on several bikes in the past. I usually get overwhelmed by the endless possibilities for adjustments (analysis paralysis).... I ride about 50/50 street/track. I don't race...
