Personally I'm not a fan of DAS.
If you havent ever ridden a bike before, can you reasonably expect to become competent on a 5 day course where you will be likely sharing the tutours attention with 10 other people? How much actual road riding experience are you likely to get?
Personally I would find yourself a good 1 on 1 instructor and do lessons over a period of months. You will learn a lot more, and ultimately be safer.
Anyways Lt_Red's post is spot on
But to add and reiterate a couple of things:
If and when you pass, I would certainly suggest further training, preferably on a 1 on 1 basis. There are loads of advanced instructors and the police run bike safe courses are worth a look.
Generally you want to avoid 'pack' riding. Riding in a group is nice but I would suggest that as a new rider it may encourage you to ride beyond your ability and that can end in tragedy. Of course you can learn from other bikers, but I personally always ride for myself and dont try and mimick their ability.
ALWAYS ALWAYS ALWAYS wear your protective gear. Gonna be 2 minutes to pop to the shop for some milk? WEAR YOUR GEAR!! Even at 30mph the tarmac will take your flesh down to the bone in seconds. I have met some young but seriously messed up lads because they 'just popped out' without their gear on. As mentioned your gear is a last resort but it can save life and limb. My dad still has a leg because he was wearing his gear during a very nasty biking accident. To that end, get the best quality gear you can.
Never rush or hurry. Thats how you end up dead. Never be pressured into doing ANY manoeuvre that you are not comfortable with. Thats how you end up dead.
Keep your distance. SOOOOO many riders get sucked into sitting on the back bumper of a car when they are in traffic. Even a low speed nock will probably leave you with broken wrists and a broken bike. Higher speed ones will leave you in a box.
Never go belting around corners that you cant see around. Sounds like page 1 stuff but so many bikers fall foul because there is a stationary vehicle or something pulling out from a concealed entrance.
Ride a defensive line.
Make yourself as visible as possible - ride with your headlights on (older bikes are not hard wired on), wear high vis clothing and try not to position yourself in blind spots.
NEVER overtake if there is a junction anywhere near you, even if its on the opposite side of the road. I saw someone get seriously hurt because they did an overtake with a T junction to their right. The car driver came out of it looking to HIS right for oncoming traffic because he was turning left. He didnt look left to see the biker making a risky overtake so pulled out and BAM. Lights out.
Nearly happened to me when I was a new rider and a bit green behind the ears too.
ALWAYS beware of blind crests and hidden dips. Pay attention to the road signs and approach such areas with caution. If its a big dip it can conceal a HGV and if you pull out to overtake at the wrong time......Dead. Likewise, blind crests can lead into dips and there can be stationary vehicles or junctions so approach with caution.
Learn how to read the road and learn how to use vanishing points. Try and develop your forward hazard perception and try and see things happen before they do. Experienced bikers appear to have a 6th sense, but it takes time to develop it. Use markers to help when reading the road, such as tree lines, hedgerows, telegraph poles etc. they caan all help to give you an idea of where the road is likely to head and whether it has other roads leading into it (IE potential junctions).
Know your bike. Inside and out.
Expect everyone to pull out on you. Expect everyone to not use their mirrors. Expect everyone to suddenly brake for no reason. Expect everyone to trry and kill you, and ride accordingly.
REMEMBER - in the city road markings and signs will most likely be accurate, however out on the open road please read the road as well as using road signs. Just because there isnt a sign for a bend or a junction, does not mean there isnt one there!
Finally, never use the rider in front as a focus point, because A) he might be a bad rider, and B) it narrows your own hazerd perceptions down to a tunnel vision like state. On this note - I nearly died because I did this. I was following my brother and he took a nice left hander on a country B road. I mimmicked his line, and saw he hadnt braked so I didnt either. As soon as I entered the bend I knew I was in trouble. I ran wide into the oncoming lane and stopped a foot short of an oncoming tracter with 2 big metal prongs on the front of it. I was lucky because A) he saw me and slowed down, B) he wasnt a car, seeing as it was a 60mph zone. If he had of been I would probably be dead.
It turns out my brother DID brake for the bend, but his brake light bulb had popped earlier so didnt light up. Theres a moral in this story if you want to look for it
Have fun and good luck
Cheers
