2020 Honda CR500RA ultralight prototype v2.0...the lightest wheels possible, front tires update with a super light new Michelin Sorry for the delayed post…trying to get back on track since most of my time has been consumed with non-moto work and working on a new shop/home in SoCal. This bi-coastal thing is a time killer…but we’re getting there. Now, off to a front tire update in the industry. There is a new lightweight king and we now have a match for the worlds lightest rear MX tire which is also a Michelin New front tire lightweight king as of ~Jan. 2021 is also a Michelin, de-throning the previous king by Metzeler, the 6-Days Extreme 80/100-21 at 7.725 lbs. (3504g)…by nearly 1/2 pound Front tire: Michelin Starcross 5 Soft 80/100-21 7.290 lbs. (3306g) Rear tire (still the lightest): Michelin Starcross 5 Soft 100/90-19 9.155 lbs. (4152g) #cr500 #cr500r #cr500ra #cr500af #500cc #500 #2stroke #twostroke #openclass #honda #hrc #cr #motocross #enduro #gncc #mx #gp #factory #lightweight #weightnerds #carbonfiber #titanium #supercross #michelin #suzuki #yamaha #kawasaki #ktm #husqvarna #gasgas https://www.instagram.com/p/CSSO70-L5wG/?utm_medium=tumblr

2020 Honda CR500RA Ultralight project v2.0...pipes/silencer finally arrived and in place. I’ve been working with @1744_racecreations on this one for a while and it arrived while I was traveling for a bit…so just got my hands on it and I just love it…all of it. It fits like a glove and I can pick it up with my pinky finger 😂 at 1436g Two pipes…one is raw/pure Ti and the second is blue anodized/burned. The silencer is a work of art made of all Ti and carbon fiber….so very light at 882g We put a plate on it as a tribute to Bayle @jmb111.jeanmichelbayle #cr500 #cr500r #cr500ra #cr500af #500cc #500 #2stroke #twostroke #openclass #honda #hrc #cr #motocross #enduro #gncc #mx #gp #factory #lightweight #weightnerds #carbonfiber #titanium #supercross #1744_racecreations #suzuki #yamaha #kawasaki #ktm #husqvarna #gasgas https://www.instagram.com/p/CPMDChdA5-0/?utm_medium=tumblr

2020 Honda CR500RA Ultralight project v2.0...pipe/silencer update. Here is another peek 👀 at the full Ti/Carbon exhaust (double set...one blued and one clean/pure Ti). It is uber-light. As stated earlier, its cloned after J-M Bayles RC500 pipe design 🚀 from PC. I’ve been working with @1744_racecreations on this one for a while. We had to re-spin it one time to get it perfect 👌. Good things take time. I’ll make a few more posts showing how it all came together soon...the design process and the progression...the the total weight 😉. Do you wanna see it all? Let me know #cr500 #cr500r #cr500ra #cr500af #500cc #500 #2stroke #twostroke #openclass #honda #hrc #cr #motocross #enduro #gncc #mx #gp #factory #lightweight #weightnerds #carbonfiber #titanium #supercross #1744_racecreations #suzuki #yamaha #kawasaki #ktm #husqvarna #gasgas https://www.instagram.com/p/CNRCwBGg7Gx/?igshid=sl8sfeipujux

OK...looking for some help with this one. Need someone that can CNC Ti 6Al4V for a countershaft sprocket. APICO used to make some...but non-existent now. I prefer the design of the first pic (custom part). I can harden/cryo if the maker doesn’t have the capability. DM please... #cr500 #cr500r #cr500ra #cr500af #500cc #500 #2stroke #twostroke #openclass #honda #hrc #cr #motocross #enduro #gncc #mx #gp #factory #lightweight #weightnerds #carbonfiber #titanium #supercross https://www.instagram.com/p/CK1k6sFgE6j/?igshid=17aomhzv0it

2020 Honda CR500RA Ultralight project v2.0...foot peg and mount update. Previously I had the lightest pegs you can buy on the market, the Al Flo pegs with stainless tips. They were lighter than all the other Ti offerings in the market since no one is being that careful with the amount of material they are using and they are overly thick and unnecessarily heavy. But...what about pegs you can’t buy 💡 👀. Through a contact I have I was able to get a set of factory HRC Ti pegs/mounts 🍾🎉🔥. I managed to scrape an extra 0.52 lbs. with the HRC Ti peg + Ti mount combination over the Al Flo pegs with modern 2016+ CRF mounts. I already had Ti pivot pins and bolts. The HRC factory pegs (96g) /mounts (59g) are super light, carved out in every possible corner/cavity...nothing else even comes remotely close New: 310g Previous: 544g Delta: 234g / 0.52 lbs See pics for more individual weight details and comparisons More trickery to come as we head towards a 190 lb. dry weight 500 with some things never seen before #cr500 #cr500r #cr500ra #cr500af #500cc #500 #2stroke #twostroke #openclass #honda #hrc #cr #motocross #enduro #gncc #mx #gp #factory #lightweight #weightnerds #carbonfiber #titanium #supercross https://www.instagram.com/p/CKcx254gES5/?igshid=uzfstamz7gyc

One of the coolest things on the CR500RA ultralight build for me is the custom carbon fiber head stay @legacycarbonmx did for me. It’s amazing how this 503cc two stroke monster feels so smooth and vibration free with this plus the @crankworksinc crank balance and match, and the 90mm piston and the 2000 CR250R digital ignition stator + flywheel. #cr500 #cr500r #cr500ra #cr500af #500cc #500 #2stroke #twostroke #openclass #honda #hrc #cr #motocross #enduro #gncc #mx #gp #factory #lightweight #weightnerds #carbonfiber https://www.instagram.com/p/CJWZ1WrgTMC/?igshid=w90zsnoucwox

2020 Honda CR500RA Ultralight project v2.0...brake rotors revisited. Motostuff v1 blade brake rotors are the lightest on the market and my favorite, but after some discussions with both @motostuff_com and @racetechtitanium, Racetech Titanium offered to work with me on a custom Ti set with my design input. Here is the result...they should have them for sale relatively soon. This will be their first Ti rotor offering for Honda CR/CRF...long overdue...here we go Motostuff blade v1 280mm front rotor: 501g Motostuff blade v1 240mm rear rotor: 419g Racetech Titanium 280mm Ti front rotor: 324g Racetech Titanium 240mm Ti rear rotor: 274g 920g - 598g = 322g (0.71 lbs.) gone from unsprung weight...pretty huge I wanted to stay oversize (280mm vs. stock 260mm) for the braking power, and hardened/heat treated Ti rotors offer a bit less friction than hardened/heat treated steel...so let’s keep all the stopping power we can and drop the weight, which is what this project is all about. #cr500 #cr500r #cr500ra #cr500af #500cc #500 #2stroke #twostroke #openclass #honda #hrc #cr #motocross #enduro #gncc #mx #gp #factory #lightweight #weightnerds #carbonfiber #titanium #brakes #motostuff_com #racetechtitanium https://www.instagram.com/p/CFihTdoAU_T/?igshid=14yleigfkazjn
