RKExcel Added a reply to New spokes
10/27/2017 10:46am Omalley, Exactly like what BobPA said, you don't need much to enlarge the holes. Our Excel rims are drilled to 8.5mm hole diameter. The Excel Spline nipple's body diameter is 8.30mm. The nipple body is the part between the butt of the nipple and the wrench contact point of the nipple. For my personal preference, I would use the step...

RKExcel Added a reply to New spokes
10/26/2017 8:29am Omalley, None of the Excel spoke/nipple kits will require you to drill out your stock OE hub. For your 2002 CR250, the front Excel spoke/nipple kit will require you to drill the stock front OE rim's nipple hole diameter to an 8.5mm as majority of our Excel rims come with the 8.5mm nipple hole diameter. From a quick search, it...

12/14/2017 8:09am DLC, Everything looks correct for chain length with the 13/50. Which model RK Chain did you installed on the bike? MXZ4? MXU? The information should be listed on the side plates of the chain if you do not have your order receipt from when you bought the parts. Do you mind sending me some photos of the setup? Cole Anderson...

6/29/2017 2:22pm DJC, If you can provide me with some more information regarding your situation, I will see if I can determine the issue you are running into. First off, what is the year, make and model motorcycle? Front and Rear sprocket tooth size along with chain length? How is the condition of your front sprocket? New, used, hooked teeth, missing teeth...

4/11/2017 10:43am You shouldn't have any issue putting a 2005 RM250 rear wheel on the 2006 RM125. The hub and wheel spacers are the same. However, the RM250 comes with the 19x2.15 and the RM125 comes with the 19x1.85 rear rim. Cole Anderson Racer Support Supervisor RK Excel America Inc

12/14/2017 8:11am Our Excel rims do not require you to use our Excel Spoke/Nipple Kits but our nipple hole diameter on our 21/19/18 Excel rims are an 8.5mm. FYI..... The Excel Takasago Signature Series and the Excel A60 rims use the same nipple hole diameter and drill pattern. Depending on the motorcycle manufacturer, the front stock OE rim comes with a slightly...

12/14/2017 8:11am What CRC245 said! You will need to increase the cross pattern to the stock OE 3 cross. I have photos of a 3 cross if you will like to shoot me an email. Offset is 26.50mm for the front hub. The rear hub will be the stock 2 cross with the long spokes as the inner spokes and short spokes...
RKExcel Added a reply to Yz250 a60 necesary spokes?
12/14/2017 8:11am Hi Ben, For your 2015 Yamaha YZ250 (2T), I am assuming you are using the stock OE rims sizes (21x1.60 36H Front, 19x2.15 36H Rear)? For the front Excel A60, the stock OE spokes will work fine however you may need to replace the nipples to a larger diameter nipple. The stock OE front rim that comes on the Yamaha...
RKExcel Added a reply to RK Chains for 125
11/16/2016 12:32pm VxEr, The RK Chain spec sheet is for consumers to have more information regarding the series of chain they are going to use for their motorcycle. This allows for riders to pick which product to use based on the chain specs. The engine displacement rating for each chain is listed because our RK Chains are used on a variety of...
RKExcel Added a reply to Question For You Wheel Experts
10/25/2016 12:39pm It actually depends on the Excel Rim part number that you choose. Some part numbers are drilled for certain aftermarket hubs and some are drilled for stock hubs. The part number for stock hubs would be FE_422 18x2.15 36H drilled for stock Yamaha. The underscore will change depending on the color of the rim. For example Silver would be FES422...
RKExcel Added a reply to Question For You Wheel Experts
10/21/2016 12:16pm You can use the stock OE spokes however the stock OE nipples are designed for the stock OE rim's nipple hole diameter. Majority of the Excel 21", 19", 18", 17"(supermoto) rims for the big bikes all have an 8.5mm nipple hole diameter. The stock nipples do fit in the Excel rim however, there have been cases of people pulling the...

9/19/2016 11:56am Just an FYI, your C-clip on your chain is backward. I would recommend flipping the C-clip around to prevent the clip from coming off when it rolls through the chain guide and rollers. Other than that, killer build!! - Cole Anderson Race Support Supervisor / Sales Representative
RKExcel Added a reply to Yamaha wheel interchangability
6/14/2016 10:59am The wheels are interchangeable but the YZ250F has a 19x1.85 and the YZ450F has a 19x2.15 rim width.

Just for the record, the chain you show (RKM 520H) is NOT suppose to be used on off-road bikes. You should be using the MXZ4, MXU or EXW chain.

11/12/2014 8:28am Yeah it is an excellent product. But unfortunately the high price tag would prevent most users from trying it. We'll keep you posted if we do eventually bring it to the US. Cheers, Farrah Bauer Marketing & Advertising Manager RK Excel America Inc
