So our CMRA ULW Endurance season is over. We only did 2 races on the R3, but it was a blast. Cant wait to start again next year.

We were at Texas World Speedway, which is a track I love. The track might be bumpy and old and needs to be repaved, but there is so much history there and its an absolute blast to ride. We couldnt have asked for nicer weather for the 6hr race. We had only done one race in the series, so we were way behind on points. We started in 33rd place out of 37 total entries and dead last out of 17 in our class. After 6 hours, we managed to scratch our way to 4th in class and 10th overall. Cant really complain about that!











This tire has seen better days. After 6 hours on the same rear tire, its a lot better than some of the other teams

Nice job. Endurance racing is a blast. Our team just wrapped up a season of lightweight endurance racing on a 250 Ninja in Ontario and we had a great time. Next year we'll likely be on a R3 powered purpose-built endurance racer.

Nice! We were on a CBR250R for a few years but switched to the R3 this year. The 250 was fun but even with a 305 kit, it couldnt hang with the Ninjas on the straights.

Our main competition was a CBR250. They made all six of the rounds and we went to four. They finished every time and their consistency won them the championship. We had two firsts and two thirds and wound up third in the championship by one point. Both third place finishes were in spite of crashing on DOTs in the rain. Now that we know how good the full rains are for the lightweight bikes we're changing our general strategy to make the switch to full wets at the first sign of rain. I was amazed at how grippy rain tires are, and with the low horsepower of our small bikes even if things dry out the tires will last a long time. I just have to work on the quick change hardware to get the wheel changes under 3 minutes ;)

There was also another team with an FZR400 that mostly ran with a fast dad and not-so-fast daughter. We couldn't hang with the dad on the straights with the (maybe 30hp) 250 Ninja so I think that the significant power increase of the R3 motor will help somewhat.

6hrs on a single set of tires! I imagine the grip levels wouldn't have been great towards the end.
I'ld love to do something like this but I'm not aware of anything over this side of the ditch

Can't speak for Dav810, but we got phenomenally good tire wear without a noticeable loss of grip over the course of the four 3hr races we did and we had a pretty fast pace. That is grip in the dry. Grip in the rain on the Pirelli DOTS wasn't that great. Not bad, but not great as we did give up some pace to the guys on more street-oriented DOTS in the wet.

I rode during hour 3 and hour 6. During hour 3, my fastest time was a 2:05. During hour 6, my fastest was a 2:07. This was on Pirelli DOT's 120/150. Excellent grip even with the edge of the tire looking like it did. :)

Sounds exhausting riding at race pace for so long but the good kind of tired of course.:D

I noticed in photo # 2 that you don't have a gas cap? Is it plugged internally with a one-way valve for speed filling?

Actually, riding a lightweight bike for an hour really isnt that bad. Its tiring, but after a few minutes of sitting, Im ready to go again. Now, racing big bikes (600s & 1000s) is way different. Throwing a big bike around gets tiring and wears you out quicker. Lightweight bikes are, well....lightweight, so its not that bad. Another aspect is the heat. When we are racing and its 105 degrees, it just sucks no matter what youre on. I really like endurance racing because you get a ton of track time, whereas sprint racing is usually less than 8 laps or so. I always encourage people to start off endurance racing because its a better bang for the buck and you get more experience with less risk (relatively).

We do run a dry break in our tank for faster fuel stops. It has springs inside that push the valve up to plug the hole. The fuel can has a male end that pushes the valve open and dumps the fuel. It fills the tank in about 15 seconds. We usually get about an hour and 15mins on a tank so fast fill ups are helpful. Its not necessary, but it helps.

Thanks for the replys.
Some laugh a little when I tell them it's an 320cc but until you ride it and feel how easy it is to move it around and a joy to ride comfortably they just don't know. I rode my R3 for an hour once and got off it and walked around a little and ready to go again so I'd have to agree with you about what you said. After riding a brand new R6 on Saturday it was a little harder to turn in the corners like you said than the R3.
