Fastest 80/105 you owned

I was a 125cc racer at Saddleback back in the 80's, but a lot of my friends were the former mini stars and I tried a few of their bikes. The fastest one I ever rode was my friends 83 KX DMC 105. That cylinder and pipe was part of the White C27K Dave Miller made for Mouse which he rode at 83 Ponca that year. My friend just signed with Honda to race the pre-production CR80's at Ponca in 1983 and Miller wanted the parts back. I think the DMC 105 had a Klemm airbox on it.....very fast, felt like a little 250!

I REMEMBER MY BIKE WAS BROKE SO SCOTT BROWNS DAD LET ME USE HIS PRACTICE BIKE I WANA SAY 85 CR 80,WAS SUPOSE TO BE THE FASTEST STOCKER IN THE WORLD,I MEAN IT WAS FAST,I REMEMBER GETING THE HOLE SHOT AND NO ONE COULD TOUCH ME,AND HE HAD SEVERAL BIKES,RESEARCH BIKES WITH CARBON FIBER TANK AND SUB FRAMES THOUGHS WERE THE SHIT

1980 R&D RM80 can you say HOLESHOT!

1983 105cc DMC Kawasaki... Hands down!!!!!!!!!!!!!!!!! Thank you...

Were you getting support from R&D back then? Healey was there in 84 after he won 83 Ponca I think. They used to do my suspension on my bikes back then.

Rudy Sr. at R&D said that the 1983 KX80 (105) was miles ahead of what they were doing at R&D at the time. He said that it took them a long time to catch up to the Kawi, it was that good.

I raced a stock 83 KX 80 in 1983 after racing Yamaha's from 1980-82. I couldn't afford a new bike in 84 so we had it fully modified by Pro Circuit and it was more than competitive. Kept it as my modified bike in 1985 (when I got a new 1985 as my stock bike). That 83 was still one of the fastest bikes in the field no matter who was there. The 83 KX80 was a great bike, it was like getting a factory bike (to me after the 82 Yamaha). I couldn't imagine how good the 83 DMC KX 105 was! Only in my dreams....

I was much like you NW#599- I also raced YZ80's from 79-82 including the 82 YZ80 with the first water cooling.
However- in 83 I was really too grown for 80s anymore. Fortunately the 83 KX80 was tall enough to convince my Dad to milk another year out on an 80.

The 83 KX80 was a rocketship-- even stock. It also had way more bottom end then I think any 80 had ever had up till that point, which certainly helped lug my quickly growing patoot around the track!

Mine was fairly stock, with some mild engine tuning & the Klemm airbox that made a HUGE difference. Those boxes were also a nessesity not only in performance, but because cleaning the filter with the stock airbox was an absolute nightmare. I recall it was easier to remove the complete airbox to clean the filter rather than fighting that poor design. I certainly polished up on my young profanity in the garage with that stock airbox!

I also never rode a highly modified DMC/Pro Circuit/Etc 80, but I can say in my experience the 83 KX 80 was definately the fastest 80 I ever rode/owned.
