I'm working an aftermarket product development project. A critical aspect of this is to get beyond my own preferences so that I have some confidence that I'm answering to what others want, and not imposing my own "stuff" on the project. I'm learning as I go about what riders and serious racers are looking for when they replace parts and upgrade their rides. I need your help to be sure that I'm getting past my own biases. I've engaged in several sprocket/chain threads - everything from maintenance, to lubes, to replacement brand preferences, etc. When it comes to replacement sprockets, I think I'm seeing that most riders are more concerned with durability than with minimizing weight. I see lots of comments where steel sprockets are the preferred aftermarket choice - even on bikes that had aluminum as original equipment. That implies that the added pound of weight doesn't bother riders as much as the shorter life of aluminum. Certain characters here are more outspoken than others, so I'm not sure if what I think I'm seeing is really a good representation of the majority. So I have this question: Knowing that a steel rear sprocket typically weighs approximately 15-18 ounces more than an aluminum sprocket of the same size, and, knowing that a steel sprocket will outlast the typical aluminum sprocket by 2x to 3x, which would you choose as a replacement for whatever is on your ride now? Please let your opinions be known! And if you would, please mention the kind of riding you do (MX, ST, DS, etc.). Much appreciated.

Hi everyone so I was thinking of painting my rc valve and stator cover matte black. In terms of heat I know they shouldnt get more than 400F so I decided to go for the 2000F black paint as its matte and look very good. But after painting it and heat curing it, it seems like its no very durable as even finger nail is marking it so rocks would be worse. I know that I can buy high heat clear coat so i was wondering which one would be better in terms of durability the 500F matte clear coat or the 2000F clear coat. Any input/experience is appreciated I still have to take of tape residue off the shiny part but it looks wayy better in person ngl

Hello All...figured I'd take a break from my own bike to ask a question related to my son. He'll be turning seven this summer, and has pretty much outgrown the '94 JR50 I built for him. Both feet are flat on the ground with knees bent, with the shocks and rear seat posts in their highest positions. Now, the JR is a notoriously short bike (18" seat height in lowest setting), and I'm thinking something in the height of a CRF50 or KTM SX50 Junior would be correct for him...and I can put a "tall seat" and risers on that to keep him on the bike if he spurts before the end of a second season. The challenge I'm facing is finding the right bike for him with the kind of riding he wants to do in our area. He wants nothing to do with the track, which is fine by me. His request is to get into single-track/GNCC/TORCS-type aggressive riding with me here in central Texas (rocky, technical, cactus needles, hand-bashing, 10+ mile loops, 100-degree afternoons all summer long). If I look at a CRF or TTR, I get a heavy bike (hard for an almost-seven-year-old to muscle over rocks and tree roots) with spring-only suspension, drum brakes and a 10" front wheel that stinks outside of a groomed track or back-yard trail. If I look at KTM or JKS (Polini clones) in the "junior" heights, I'm looking at a bike that fits, is light, has better suspension and brakes...but that would likely overheat quite a bit in slow technical sections and has a reputation of eating clutches even on a track. I can't imagine how they'd hold up to partial-throttle off-roading over two seasons. We won't be able to just walk back to the truck in the pits for spare parts like in the MX world...things get serious multiple miles from camp. If I go with a Chinese equivalent (SSR 70C), I get slightly better suspension that can be tuned, hydraulic brakes and the ability to run a 12" front wheel for better behavior in loose rocks and roots...but I also get worries regarding durability when we get serious off-road (legends of Chinese metallurgy and QC). So...to the parents that "do the desert" or get serious off-road with youngsters (at least at the "family enduro" level) in hot-weather environments... What is the best option for a bike that will last two years, has about a 24" seat height and will work with an aggressive boy who wishes to attack "hill country" the way most boys want to attack a motocross track?
