Hi all, I am looking to do my CBT in the next couple of months and get myself a road bike but I also want a motox bike for taking to local tracks but I can't afford both so I was thinking about getting a supermoto 125cc, I am only 5ft 4in so I need something I can fit on, also when you own a supermoto do you have to change the bike depending wether you are off road or on road stuff such as wheels/Tyres and gearing ? What bike would you guys recomend I will use the bike to get to work and back which is about 4 miles all round and also for off roading on weekends ? I will have about £1k - £1.5k to spend maybe less

Hi, I had a yamaha dt 125 re. It had nobbly tires on so was more than capable off road. Not mega fast though and can't imagine it would be great on track.

Other bikes.. KTM EXC 125.. you could have 2 sets of wheels one with sm tires and the other with nobblys for the track.

Husqvarna wr 125, https://www.youtube.com/watch?v=VRzohP_VUfk same as above really these bikes are quite high maintenance though so I wouldn't imagine they would be great for commuting.

Apart from that really there's not many 125's which would be suitable for both track and road.

How about getting a cheap commuter (200-300 quid) then having a motocross specific bike?

By the way you will need to change the tires on a proper MX track supermoto tyres won't cut the mustard.

Anyway hope that helps.

Hi are you wanting a trail type bike or mx for your offroad stuff.

If you're taking the bike to motocross tracks, the KTM/Husky will handle that fine - I'd go for the KTM for ease of availability of wheels etc.
You'd just have to swap the wheels, chain and caliper bracket over.
However, for a start it would not only be illegal to ride on a CBT, it'd also be illegal to ride on a 33hp licence. Whether that should bother you or not is another matter.

They don't come with an ignition barrel at all, or a steering lock - so gonna want a big chain where ever you are really.

If you've got transport for your bike and it's motocross you want to do, two seperate bikes would be better I reckon - you could get a DT125 and a CR125 for £1.5k all in and have more suitable bikes with less worry of damage to one causing problems for the other (too much use and breaking down so you can't do mx, or crashing mx so you can't commute.)

I had a Suzuki RG-80. I thought it was great at the time. The best I got out of it was about 95mph. Going downhill. With a wind behind me. Course I was about two stone lighter then, so I would probably get barely 40mph out of the same bike now!

Yea, was just pointing out that it probably wouldn't even be legal if he DID pass his restricted test, nevermind for 14.6hp learner limit!
The 33hp restriction also has a power to weight limit, which I believe even with under 33hp, these bikes are quite likely to break as they tend to be pretty light.

Apparently it's .16kw/kg - which is .21hp/kg.
So a 100kg bike (new 125EXC is a little under this no fuel, older ones a little over) should technically be limited to 21hp or so - maybe a bit more if you include fuel. Seen outside sources suggesting 35-37hp for them, which doesn't seem too unreasonable - feels about right from my 200 which has a tiny bit more top end than the 125 it's based on.
